Hello all.
I'm playing with an umsm(4) device from Longcheer (as USB ID says). After
adding corresponding lines to usbdevs and umsm.c it still doesn't get
ucom(4) attached.
I tried all 4 umass quirks, DEV_UMASS[1234]. Steps were the following:
1. Build kernel.
2. Make sure modem is attached.
3. Reboot.
4. Boot new kernel in single user mode.
5. Look at the "umsm0 at" message.
6. Remove modem from slot and see "umsm0 detached" message.
7. Put it in another USB port and see "umsm0 at" message.
8. Realize I'm out of luck and use another quirk.
9. Go to (1).
Once (when using DEV_UMASS3) it showed the following on booting:

After reboot it was quiet again.
Could anyone give me a clue(stick) how to debug and fix that behavior?
The patches to usbdevs and umsm.c are at the end of letter.
"usbdevs -v" always show 0xf000 product ID; sorry, I forgot to run it
when three umsms and ucoms were attached. :(
The USB_PRODUCT_LONGCHEER_U12 code was taken from MS Windows Device
Manager (the modem runs fine there).
I'll try to buy another one but dunno how to send it to interested
person - I live in Moscow, Russia now.
