    You need a type-c to USB adapter and you can use hubs. Charging type c should work, apple has one I used and it let me use the USB ports and charge my Xiaomi Xi Pad 2, the Chuwi Hi8 Pro should be the same.

     

    Something like this:

    Or

    http://www.banggood.com/USB-3_0-Type-C-3-Ports-Hub-Data-Sync-Charging-Adapter-Aluminum-For-MacBook-p-1005118.html should work.

    I ordered this adapter: http://www.gearbest.com/tablet-pcs/pp_260755.html

    Once I receive my Chuwi from DX, I will tell you if it works as advertised 🙂

    IMPORTANT WARNING : NEVER use a PSU with a higher voltage output to power/charge a device that requires less voltage than that what the PSU outputs !!! 😮 😮 😮

    More amperes is fine, but more volts is DEFINITELY NOT OKAY and will most likely KILL your device.

    IMPORTANT WARNING : NEVER use a PSU with a higher voltage output to power/charge a device that requires less voltage than that what the PSU outputs !!! ? ? ? More amperes is fine, but more volts is DEFINITELY NOT OKAY and will most likely KILL your device.

    In general, this is very good advice. However, USB-C is an exception. USB-C can provide up to 100 watts of power, and it achieves this over reasonably sized cables by increasing voltage. More than you ever want to know linked below, but the short version is that USB-Power Delivery over USB-C could be 5, 12, or 20V, at up to 5 amps. At maximum output, the Apple MacBook adapter is 12V at 3A, the Chromebook Pixel adapter is 20V at 3A. The important point is that the device negotiates with the power supply to get what it can handle.

    https://en.wikipedia.org/wiki/USB#USB_Power_Delivery

    The downside of this is that non-compliant cables and adapters can cause issues by lying to the host or power supply. A Googler named Benson Leung is doing an amazing job of testing good and bad cables and accessories, and building something of a community around him doing it. Resources here: https://www.reddit.com/r/Nexus6P/comments/3robzo/google_spreadsheet_for_usbc_cables_with_benson/

    Having said, that, none of the adapters linked in these threads are power supplies, so I don’t even really understand the rating on the product page. I’ve used an adapter that looks a lot like the Gearbest adapter (likely the same ODM) on my Macbook with the Google adapter and had no issues at all. I’ll test on the Hi8 Pro later this week when I can play around with it for my intended purpose: VCDS and HP Tuners.

    I should have tested more carefully before. It turns out that my adapter like the one listed doesn’t actually charge either a MacBook or the Hi8 Pro. I’ve now tested with: USB A-C cable plugged into an Anker charger, Apple charger with original cable, and a Google charger (which has a captive cable). I’ll keep you guys posted as I test more adapters.

    It seems the one I ordered (http://www.gearbest.com/tablet-pcs/pp_260755.html) does not work with the chuwi 🙁 any luck with other adapters?

    Yes. I’m trying to find a similar solution.  I’ve tried this : http://www.amazon.co.uk/2-Port-Aluminum-MacBook-Chrome-Devices/dp/B017CMOES2/ref=sr_1_5?ie=UTF8&qid=1456057260&sr=8-5&keywords=usb+type-c+charging+hub  This reviews as offering OTG hub + charging functionality on a Chromebook Pixel and a Macbook.

    It wasn’t entirely successful.  No charging through it, but I needed to connect a PSU to the USB Type-C power input to get any hub functionality.  Even then this may have been limited to USB 1.1 as whilst a keyboard worked, external hard drives (self powered and bus powered) didn’t.

    My tablet didn’t indicate it was receiving power over USB when connected either.

    I received numerous USB errors, including one about power surges, and have tried both the Chuwi PSU and supplied cable and alternative USB Type-C cables (which are properly USB Type-C certified with the correct power handling that Benson Leung has been testing for)

    So far – no joy.

    Have ordered a couple of other solutions (a standard OTG cable for USB A-female to USB Type C and an inline single output charge + OTG adaptor – but it looks similar to the one mentioned above so not expecting it to work)

    Chuwi customer support confirmed to me that the connector is USB Type-C 3.0 (i.e. it is USB 3 not 2.0 they say…)

    I have asked them for a recommendation for an OTG+Charging solution.   I also asked if I needed to change USB BIOS settings (I had to do this to get my Linx 7 to reliably charge AND run OTG at the same time using USB Micro-B OTG charging hub solutions) and was told not to touch them (I am always wary as if you lock yourself out of USB in the BIOS you can’t change BIOS settings…)

    Does seem like USB Type-C has a number of ‘early adopter’ issues.  Witness all of the cables that currently fail to meet USB Type-C approval.

     

    Has anyone :

    1. got USB OTG working reliably with USB 2.0 or 3.0 devices and a Type-C OTG adaptor
    2. got USB OTG AND charging at the same time with the above and/or a charging hub.

    I can confirm that this device doesn’t work either for OTG or as a Hub : http://www.amazon.co.uk/gp/product/B017KBQLPO?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00

    I can confirm that this device works as an OTG adaptor : http://www.amazon.co.uk/gp/product/B011BASJQ4?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00 and allowed me to connect both a USB 1.1 mouse and a USB 3.0 2.5″ Samsung 1TB external HD (with no external power and I was able to play video from the drive). I can’t confirm if the connection was USB 2.0 or 3.0.

    So the search for a Charging Hub with USB OTG continues… (Unless the Chuwi has been poorly designed so that it can’t do both)

    Update :

    When I connect a USB 3.0 powered hub, or a non-powered USB 3.0 hub with integrated Ethernet, into my USB Type-C to USB 3.0 OTG cable I get USB Device unrecognised errors. If I connect a USB 3.0 HDD directly it works fine.

    When I connect a USB 2.0 powered hub to the same OTG cable it works fine AND the USB 3.0 hubs above then also work fine (albeit USB 2.0 compatible)

    My USB Type-C Hub + Charging adaptors are both USB 3.0. The Chuwi appears not to like them. Is there such a thing as a USB 2.0 Type-C Charging hub?

    A few people have suggested using USB-A to USB-A cables to back-power through a non-powered Type-C to USB 3.0 Type A multiple output hub. This provides charging to the Chuwi but you can’t connect it until after boot-up (it hangs the BIOS), and you don’t get any USB hub functionality – just USB device unrecognised error messages.

    There is something wrong with the Chuwi Hi8Pro’s USB Type-C implementation I fear.  Devices that work fine with other USB Type-C computers (MacBooks, Chromebook Pixels etc.) aren’t working with the Chuwi.

     

    So far it appears impossible to charge and connect USB devices at the same time.  Major fail.

    I have a Chuwi Vi8 Plus (http://www.gearbest.com/tablet-pcs/pp_268587.html) and I’ve bought this cable:

    http://www.dx.com/p/cwxuan-usb3-1-type-c-to-usb-2-0-2-port-hub-micro-usb-otg-adapter-cable-black-400866

    It works as USB 2.0 OTG HUB, but doesn’t work to charge through the female microUSB type B or female USBs type A (with male A-A cable). MicroUSB type B female doesn’t work as OTG neither (it’s useless)

    What do you think about a HUB like this…

    http://eu.banggood.com/Wholesale-Warehouse-3-Port-USB-2_0-OTG-Hub-OTG-Charging-Cable-For-Mobile-Phone-Tablet-wp-Uk-970000.html

    …and an adapter like this?:

    http://www.dx.com/p/usb-3-1-type-c-to-micro-5pin-data-sync-charging-adapter-light-grey-405989#.VtGNtSrhCUk

    I’m thinking about to order it, but I don’t know if it may be useless.

     

    Thank you!

    Ive tested 2 USB C to micro A adapters (Xiaomi and OnePlus 2) , one c to a cable , one c to USB 3.1 otg cable and a hub : http://www.ebay.de/itm/181999358286

    All of them doesn´t work … i´m searching in first for a solution, that provides 2 Usb 2.0 Ports for a wireless mouse and a keyboard or a usb drive, because my Belkin keyboard cover and my Logitech M557 produces a lot of input lag.

    A charging solution would be nice too, to connect a powerbank for extended usetime.

    I think the USB c implemention is worse because of missing standards … ive similar issues on my OnePlus Two (only the Xiaomi and Oneplus USB c adapter with an ordinary otg cable works) , i don´t want to pay too much for useless cables that doesn´t work with no one of my two devices …
