[PATCH] USB: add Option Card driver
This patch adds a new driver for "Option" cards. This is a GSM data card,
controlled by three "serial ports" which are connected via an OHCI adapter,
all located on an oversized PC-Card. It's sold by several GSM service
providers.
Traditionally, this card has been accessed via the standard serial driver
and appropriate vendor= and product= options. However, testing has
revealed several problems with this approach, including hung data transfers
and lost data blocks when receiving.
Therefore, I've written a separate driver.
