[usb1208FS] usb1.USBErrorBusy: LIBUSB_ERROR_BUSY [-6] #45

Closed WillForan closed 1 year ago

WillForan commented 1 year ago

https://github.com/commaai/panda/issues/154 suggests self.udev.setAutoDetachKernelDriver(True). I tried adding that before claimInterface but that didn't help.

I'm not sure if COMEDI would be an issue, but I don't see it in the module list.
