The background:
I recently learned about OTG USB cables that can be used to connect peripherals to Android devices. I had this idea of using an android device with a usb barcode reader connected (which basically acts like a keyboard) and an in-house developed app, for stock management in a warehouse.
The first step was to buy the OTG cable. The second was to start testing peripherals connected our existing Android devices.
The problem:
When I connect any USB device to a Huawei Y201 Pro (4.0), there is no feedback from the device. No error, no response from the input, nothing.
When I connect mouse to a Galaxy S II, it recognizes the usb cable, then a cursor appears on screen and all works great. However, when I connect a keyboard (I tried around 5 so far), a notification says that the cable was connected but right after that it says that no devices are connected.
My question:
Is there something I'm missing to make this work?
If not, some secondary follow up questions: What are the things I should look for in making this idea work? Is this connectivity more dependent on the Android device? OS version? Peripheral?
