usb_modeswitch (Oneiric , Natty )

alexfish · Post by **alexfish** » 30 Oct 2011, 20:36

Have tested latest debian packages 1.9 and 1.2 on Natty assuming this may apply to Oneiric

1.9 partially breaks , mainly the hot plugging (tested with two zte devices) not sure about others have seen posts about this
1.2 can break totally
have also see post where manual switch fails , yes I know what udev is for. but have checked by disabled the switching. in the usb_modeswitch.conf , then moved the unpack the tar.gz file to /tmp/usb_modeswitch.d

then usb_modeswitch to the /tmp/usb_modeswitch.d

anyhow for Ubuntu users of the above Title, have done a post here

Can you define "1.2.0 can break totally"?

What is happening and what is not happening?

Hi Josh

upgraded to 1.9 to give it a run , OK at boot ; the hot plugging did not work ,

in 1.2 , test 2 devices 19d2:2000 and 19d2:0103 : both not switching at boot or when hot plugging

part of the err message read could not claim interface , when manual switching , here is part of the syslog

tried disable and enable the usb_modeswitch.conf and made no difference , used manual eject to get the device to switch

I have reinstalled the repo modeswitch , will re-run the upgrades as before , to get the debug files , and will post asp

as a matter of note, sakis3g will switch the devices {latest version} have also recompile sakis3g with usb_modeswitch 1.9 . no problem with the two devices, have not tried 1.2

will also post the results of Sakis3g log as well

regards

It seems there is trouble with the dispatcher variant of Ubuntu. I can't really help there, they are using a different program, not the original script. Please report this as a bug to the Ubuntu "Launchpad".

On the other hand, it seems that the file that was missing and needed to make the Debian package work, is back. It's called "/lib/udev/hotplug.functions".
So you should be able to use the unchanged Debian packages again.

Or simply use the source package. It's tested on Natty and Oneiric (and a load of other distros) and working well. Easy and quick to install - just add package "libusb-dev".

hi josh

RE : Natty
can confirm if 1.2.0 is installed the the dispatcher is the problem : remove the 1.2.0 dispatcher (seems to be an exec ) and replaced with natty dispatcher (tcl script ) solved the problem both devices now working
readers can use gksu nautilus to change the files over.

also had not noticed the the change in permissions of latest usb_modeswitch , the main errors of

Looking for active driver ...
USB error: could not get bound driver: Operation not permitted
No driver found. Either detached before or never attached
Setting up communication with interface 0
USB error: could not claim interface 0: Operation not permitted
Could not claim interface (error -1). Skipping message sending
-> Run lsusb to note any changes. Bye.

should have realized should be running sudo usb_modeswitch ((Cloth head)) : Bah. sure earlier versions did not require root

had not spotted this since I use own ui for debugging the system (a relic from earlier ubuntu verions)

got around that by

Code: Select all

sudo su

chmod u+s /usr/sbin/usb_modeswitch

thanks for the hat tip
