If you have vmware, you could do the following: turn on the usbfs_snoopOK, I get vmware to work on my gateway machine (btw. it was veeery slow - well 133Mhz :) ).
parameter (see devio.c - 2.6 kernels only); run windows on your linux box
inside vmware; set things up so vmware controls your modem; install the
windows driver; download your evil file into windows. If the modem works
fine, then that shows that there is no problem with the linux usb core -
there is a problem with the linux driver(s). What's more, you will have a
complete record of everything the windows driver did. If it doesn't work,
then that's interesting too!
Installed win98se on virtual machine, installed speedtouch drivers etc. I was able to download
2MB 0x00-stuffed file smoothly. But downloading 0xFF-stuffed file failed just as it did under pure
Linux. Well, I'm not quite sure if it's good news or bad :) . But at least we can be sure that linux
driver is innocent in this case. BTW. I ran vmware on 2.4 kernel so there was no logging enabled.
When I find more time I compile 2.6 kernel with usb_snoop support so we can see what's going on
behind scenes.
PS: Tell the windows driver not to use the isochronous endpoint.Hmm, I don't know how to do this (it never asked me) but Alcatel diag utility shows that usb uses
bulk endpoint so I guess this is OK.
P.S.: I don't know if this is related to the problem but I had problem to get modem to work on virtual host
under vmware. When I plugged modem the firmware upload began. Everything went OK, but when modem
tried to synchronize it froze (USB led on and DSL led off or both leds on). The diag utility showed yellow icon
(synchronizing with DSL line). I had to repeatedly plug the modem in for a few times before it was successfully
synchronized. Maybe it's just an issue of virtual computer (as I wrote, everything went very slow so maybe some
timeouts occured ...).
