Chris:

Dmesg shows the following at plugin of my 7290:

Usb 1-1: new full speed USB device using uhci_hcd and address 2
Usb 1-1: reset full speed USB device using uhci_hcd and address 2
Usb 1-1: usbfs: interface 0 claimed by usbfs while 'btool' sets config
#1

Lsmod shows the following modules loaded:

Vmnet
Vmmon
Ehci_hcd
Uhci_hcd
Usbcore
Joydev
Evdev

Vmnet and vmmon are modules associated with VMWare.

I tried your changes to src/common.h and that made no difference.

These are the same as the devices I have to test with.  The "device or
resource busy" error you are getting may be due to a USB module loaded
in
the kernel.

Check lsmod and see if there is anything loaded that might conflict.
libusb only needs usbcore, which might not be a module.  Check dmesg
too...
it might have useful error messages.

Your endpoints are different than mine, which is not really a surprise,
but
Barry can't handle that yet.  Edit src/common.h and set the
WRITE_ENDPOINT
to 0x02 and READ_ENDPOINT to 0x81.
