Reprobing a USB device?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

This pertains to usbip, but it is really a general usb question.

So the userspace utility writes to an attribute to identify the device to be
unbound and allow the driver to change its interal state; then, (in what I
believe to be a hack) the utility writes to an attribute of the device in
question to get the usbcore to reprobe the device and issue a disconnect.

I noticed that writing to the usbip driver's unbind attribute leaves the device
unbound, which is obviously not a good thing.

So how should this be properly handled?

Thanks,
matt
