A python library to control Busylight devices based on pyusb.

pybusylight's Issues

Can't seem to talk to the device.

I have a different vendor and product number. I have updated those. but it seems like the device is connecting but it isn't reading my messages. have any ideas? I think it may be in the buffer. is there a reason for the last concatenation in the buffer?

Can't connect to Busylight

Hi eric

Thank you for your efforts so far. But unfortunately i'm unable to connect to my BusyLight Alpha.
It's always the same error message: ValueError: Device not found

I tried it on the following systems:

1. RPI 4 with Raspian OS
2. Pop_OS
3. Windows with libusb
4. WSL (following error 8045 segmentation fault (core dumped))

libusb-1.0-0 is installed... What are futher debugging possibilities?

Thanks in advance!

No backend available

When running the test code from the readme, it throws this error:

This is the line that's failing:

Line 29 in 31f3718

dev = usb.core.find(idVendor=0x04d8, idProduct=0xf848)

[EDIT] The above line conflicts with my system's reported product/vendor IDs:

Product ID: 0x3bcd
Vendor ID: 0x27bb
