I am attempting to adapt the acm driver for use with my oewn device.
It probes the device fine, but after that the first URB submission ends up
freeing the device. Details:
At some point during/right after the URB submission uhci_interrupt gets
called and spits out the message:
interrupt, status 3, frame# 1418
process_urb gets called and in the last few lines of that function it
calls usb_dec_dev_use which is defined as usb_free_dev which then frees my
device.
Eventually the kernel oopses, but this is no suprise since the device has
been freed unbeknownst to me.
This may seem like a dumb question, but what are these interrupts? Why is
my device being freed? Thanks!
