Comment 9 for bug 259028

i was googeling because ia have a ZTE MF626 USB modem and i already tried usb_modeswitch and modprobe usbserial and everithing worked fine... but the modem disconnected after 2 or 3 minutes... sometimes longer connections... may be signal... but the thing is that i sonetimes unplugged the device and plugged back and "lsusb" showed nothing... i tried "dmesg" and showed

[ 3408.164107] usb 1-2: new high speed USB device using ehci_hcd and address 21
[ 3408.276063] usb 1-2: device descriptor read/64, error -71
[ 3408.493089] usb 1-2: device descriptor read/64, error -71
[ 3408.708099] usb 1-2: new high speed USB device using ehci_hcd and address 22
[ 3408.821058] usb 1-2: device descriptor read/64, error -71
[ 3409.036085] hub 1-0:1.0: unable to enumerate USB device on port 2

and looking for the error messages i found a russian website with some interesting things... try google translator and it understands quite well... it seems to be that the kernel has some "UNUSUAL_DEV"... and the numbers...

# cat /usr/src/linux/drivers/usb/storage/unusual_devs.h
...

...UNUSUAL_DEV( 0x19d2, 0x2000, 0x0000, 0x0000,
                "Onda ET502HS",
                "USB MMC Storage",
                US_SC_DEVICE, US_PR_DEVICE, NULL,
                US_FL_IGNORE_DEVICE),

i think this is the kernel source and they edited (commented that devices) and rebuilded and rebooted... and it works fine or kind of... or at least dmesg don't show nasty messagges...

As a comment, after unplugged my usb modem, and waited like half an hour, y plugged it back and "lsusb" show the damn modem.... so i can use modeswitch and modprobe to get connected again...

is there any chance to get an update (after a fix for this off course)... that connects me automatically?

thanks,
