[pyusb-users] Could not reset device

[Yuxuan C. <yux...@gm...>]

Hi,

I'm using this library on a Windows 7 machine, with libusb version 1.2.6.0.
When I try to reset the device after encountering an error:

ecom = usb.core.find(idVendor=0x84f, idProduct=0xc050)
ecom.set_configuration()#test writing to endpoint 0x8 repeatedlywhile True:
    try:
        ecom.write(0x8, 'test')
        print("message sent")
    except usb.USBError as e:
        print("Message failed. Attempt to reset device")
        ecom.reset()
        pass
    time.sleep(2)

I get a usb.core.USBError: could not reset device, win error: A device
attached to the system is not functioning. Error Message

As a side explanation, I'm trying to reset the device because after sending
3 messages to the device, I always get a timeout error, which then requires
me to unplug and plug in the device again. After doing some research I
found that someone had solved this problem by using the reset
functionality, which brought me here.

What am I doing wrong? Thank you very much in advance for helping.
