Package: usb-modeswitch
Version: 0.9.7-1
Severity: normal
I have on Option UMTS modem with the USB id 0af0:6971 (output of
lsusb -v attached) plugged in. When I run the command:
# /usr/sbin/usb_modeswitch --DefaultVendor 0x0af0 --DefaultProduct 0x6971
--MessageEndpoint 0x05 --MessageContent
55534243785634120100000080000601000000000000000000000000000000
(as written in /etc/udev/rules.d/usb_modeswitch.rules) I get
error messages:
* usb_modeswitch: tool for controlling "flip flop" mode USB devices
* Version 0.9.7 (C) Josua Dietze 2009
* Works with libusb 0.1.12 and probably other versions
Looking for default devices ...
Found default devices (1)

No driver found. Either detached before or never attached

Trying to send the message to endpoint 0x05 ...
Sending the message returned error -2. Trying to continue
-> Run lsusb to note any changes. Bye
This does not look like the right behaviour to me. What does
"error -2" mean? When I comment out the respective lines in
/etc/usb_modeswitch.conf, and do not use udev, but run the
command:
# usb_modeswitch
without arguments, I get:
* usb_modeswitch: tool for controlling "flip flop" mode USB devices
* Version 0.9.7 (C) Josua Dietze 2009
* Works with libusb 0.1.12 and probably other versions
Looking for target devices ...
Found devices in target mode or class (1)
Looking for default devices ...
Found default devices (1)
All devices in target class mode. Nothing to do. Bye!
Is the device really supported? Are there maybe wrong parameters?
Esp. I cannot find the MessageContent documented somewhere in the
package, so it's hard to tell, whether there might be an error.
(Minor point, which does not justify a bug report: In both
/etc/udev/rules.d/usb_modeswitch.rules and
/etc/usb_modeswitch.conf, the names of the contributors Bernd
Holzmüller, Flávio Moringa, and Jérôme Oufella are encoded in
ISO-8859-1. I believe, this should be UTF-8, right?)
