The original ipaq driver takes the first pair of endpoints and invokes ttyUSBx. So it can only handle devices which communicate on this first port. There are pocketpcs (like the yakumo delta/ mitac mio) that offer more than one comport via usb, which means they have more than two endpoints. In the case of the yakumo delta the first endpoint pair (usb comport 1) is not the right endpoint pair to do the synchronization, because the communication belongs to the second endpoint pair (usb comport 2) The patch was intended to tell the driver by an option to use the first (ttyUSB=0) or second endpoint pair (ttyUSB=1) of the pocketpc device. The current driver ignores the second endpoint pair. If i understood the udev manual it is intended to "rename/relink" devices under /dev to a "readable" name. I could not find a way to handle this problem with udev. I think an adaption in the driver is necessary to solve this problem.
