Re: [pyusb-users] USBError: [Errno None] Other error

[Bob S. <bob...@gm...>]

After further debugging and digging, it does appear that the call to
"usblib_claim_interface()" is returning the value -99, not "None".  "None"
is the output of _libusb_errno[ret] for return code -99, also defined as
LIBUSB_ERROR_OTHER.  So, the real question is, why does claim_interface()
return -99?

Thanks,
Bob
