hello,
i've got a USB modem that is a UMTS HSDPA device.
when i plug it in, it appears as mass storage device:
umass0 at uhub1 port 1 configuration 1 interface 0 "Qualcomm,
Incorporated USB MMC Storage" rev 1.10/0.00 addr 2
umass0: using SCSI over Bulk-Only
scsibus1 at umass0: 2 targets
cd1 at scsibus1 targ 1 lun 0: <GT, HSDPA Modem, 3.00> SCSI2 5/cdrom removable
that storage must be the one with drivers for windows.
it is not accessible though:
# disklabel cd1
disklabel: ioctl DIOCGDINFO: Input/output error
#

any one knows anything about how to get these devices working?
basic googling gives a linux discussions with references to an
icon_switch.c, which does some binary magic thingies, like:
memcpy(buf,
"\x55\x53\x42\x43\x70\x6e\xde\x86\x00\x00\x00\x00\x00\x00\x06\x01\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00",
0x000001f);
ret = usb_bulk_write(devh, 0x00000005, buf, 0x000001f, 1000);
if (ret >= 0 )
printf("Device change command successfully sent. Box probably
switched.\nLook at /var/log/syslog for result ... Bye\n\n");
else
printf("Device change command returned error %d", ret);
thanks!
