USB_ModeSwitch

It's been a while since my last visit here...

Hi, I am having problems getting the E1550 USB dongle to work on my OpenWrt based DWC-OTG USB port. E220, E170, E169, E1762, and E230 work great

It is a good and working E1550 as it works on both of my Fedora and Ubuntu machines.

Software version:
Kernel-2.6.37.6
usb_modeswitch-1.1.4 (I have also tried 1.1.3 and 1.1.7 with no luck)
usb_modeswitch-data-20100826 (I have also tried out 20110227)

There was a hint from annother OpenWRT user in a recent thread:

Use the -I parameter to skip the SCSI inquiry. This command seems to be a problem on some embedded platforms.

Ah, and make sure to re-plug before every manual switching attempt.

Hi Josh,
Thanks for the indicator.

Here's what I have put down in the script. However, it only works at hotplug, i.e., allow the unit to bootup first, then plug in the modem. Any idea how I can make it to switch at bootup?

ResetUSB=1

The whole "framework" of usb_modeswitch is working well at boot time on all major desktop distributions.

I don't know how it will integrate into OpenWRT - you need to have at least udev and tcl, and a fairly recent kernel (> 2.6.26) to have it fully operational.

I will post the problem in OpenWrt forum to see if anybody has seen it.

OpenWrt uses hotplug instead of udev and the kernel is 2.6.37.6.

Thanks.
