[Nut-upsdev] bcmxcp_usb / kernel 2.4.32-rc2

[Kjell Claesson]

Hi Kalle.

Yes this is normal ;-( The usblib that is used for the bcmxcp-usb driver
use interrupt endpoints, and this is not normal with the 2.4 usblib.

The usblib used with 2.4 is only able to do bulk-transfer and is not
usable with the bcmxcp-usb driver. You may find some patch for this
as i know something going on. But you have to search the net for
libusb and 2.4 kernal and interrupt endpoint.
