Hmm. Maybe the program requires usbfs to be mounted? That is usually
not done on newer Linux systems, and it is not strictly neccessary.

At least for Huawei modems the modeswitch command should be added
into the Linux kernel, so that there is no need to maintain the
separate utility.

I would suggest contributing a modeswitch patch to the Linux kernel.

Second best option would be to update the usb_modeswitch utility so
that it no longer requires usbfs to be mounted.

I'm not sure that's a universally preferred option? What if you actually
wanted to access the memory card part of the device?


You would at least need some way to get the kernel to toggle the
hardware around? I would have thought that starts to look like a
userspace utility again...?


It would be nice for these devices to work more easily though..

I believe the memory card reader is always separately available. The
issue is that at first, the device exposes only a CD-ROM with branded
software - stored internally in the modem separately from any memory
card.

Having the modeswitch in the kernel makes it work consistently and
reliably like a modem. I like that a lot.

thaks for your reply ,i tried the second suggestion but i am facing a problem when cross merging usb_modeswith 1.1.0
it fails when merging tcl (*in linking step ) the error is:
multiple definition of 'fixstrtod'.
*
i do not know why*usb_modeswitch requires to merge tcl,is there any option to disable it?
or is there any patch to fix this error?
*
Thanks.

*I tried* again with the old version and it is now working after i mounted usbfs.

Thanks Peter for your time.
