LIBUSB_ERROR_BUSY error on Linux Mint #4

Closed hamishfagg closed 7 years ago

hamishfagg commented 7 years ago

Using this tool does not work on my linux install, it fails with LIBUSB_ERROR_BUSY.

It can be fixed by adding a call to libusb_detach_kernel_driver() but I don't know enough about libUSB to make a PR.

Hello @IVData It would be helpful if you could tell where to add the libusb_detach_kernel_driver()

Probably around line 397 in xmosdfu.c. I don't know the side-effects of doing this though.
