hello there,
i have an usb modem zte ev-do that i used with kernel from 2.6.29 up to 3.5.
since 3.5, i got the following message:
[77496.664090] usb 5-2: udev 10, busnum 5, minor = 521
[77496.664097] usb 5-2: New USB device found, idVendor=19d2, idProduct=ffff

one-off prototypes.

proper driver.
[77496.670186] usbserial_generic 5-2:1.0: generic converter detected
[77496.670276] usb 5-2: generic converter now attached to ttyUSB0
i would be nice to have a driver for this device in the kernel.
the device is shipped with sources to build its modules. if i understand
correctly thet are released under GPL, so i attached them below.
this is portion of Makefile i used:
obj-m := ztemt.o
ztemt-objs := usb-serial.o bus.o generic.o ezusb.o zte_ev.o
usb-serial.c, bus.c, generic.c and ezusb.c are from the kernel source.
the patch against 3.5 i used for generic.c is also attached below.
and since 3.5, i've also got the following message:
[77694.270178] usb 5-2: uhci_result_common: failed with status 440000
[77694.272174] usb 5-2: uhci_result_common: failed with status 440000
