Hello. I use some old wireless keyboard and mouse named "Trust" with NanoPC-T4 (which runs Android for now). Recently kids "reported" me that mouse stopped working while watching youtube, I thought that bateries run out. Changed today battery and it's still not working. Looked to dmesg, and found that dongle fails to initialise. Connected it to my laptop - same story. Here's appriximately what I get in terminal:
usb 2-1.2: new full-speed USB device number 4 using ehci-pci
usb 2-1.2: device descriptor read/64, error -32
usb 2-1.2: device descriptor read/64, error -32
usb 2-1.2: new full-speed USB device number 5 using ehci-pci
usb 2-1.2: device descriptor read/64, error -32
usb 2-1.2: device descriptor read/64, error -32
usb 2-1-port2: attempt power cycle
usb 2-1.2: new full-speed USB device number 6 using ehci-pci
usb 2-1.2: device not accepting address 6, error -32
usb 2-1.2: new full-speed USB device number 7 using ehci-pci
usb 2-1.2: device not accepting address 7, error -32
usb 2-1-port2: unable to enumerate USB device

Found an info on internet, that it might be that device get overcurrent. So I turned computer off and then unplugged device Started again and plugged back mouse dongle. It started working again.
It never ever happened with me on any computer. So, might it be that NanoPC is "leaking" somehow? Can it be fixed thru software somehow to prevent "short" in USB?
