hso drivers snowball v10 + kernel 3.4.0 or 3.3.0

[craksz]

hi... i hope you could help me with this:

i want to install globetrotter hsupa modem (GTM661W)... i have the drivers and i got it running on my desktop computer...
however, i cant get it to work on snowball... but i guess this is a secondary problem:

i realized that this message displays 6 or 7 times when booting up:
modprobe: FATAL: Could not load /lib/modules/3.3.0/modules.dep: No such file or directory

but, the system starts perfectly... anyway when i run "lsmod" i only get one module running
g_multi

im not sure if this is ... alarming? lol... but im guessing that something's wrong because test codes for the - 3Gmodem - drivers (hso based), always mention hso module...

by the way: lsusb displays the modem correctly 0af0:9000 Option N.V. but i am supposed to find 6 ttyHSx devices on /dev... and ... you know... i dont find any

Id really appreciate your help! thanx!

in case anyone's wondering...

i fixed the "could not find depmod.dep" error using the linaro guide for Kernel building and deploy...

Code: Select all

# Generate a file named /boot/initrd.img-<KERNEL VERSION>
$ update-initramfs -c -k `uname -r`

# Now package and copy it into your boot partition with:
$ mount /dev/mmcblk0p1 /mnt
$ cp /mnt/uInitrd /mnt/uInitrd-bak
$ mkimage -A arm -T ramdisk -C none -n "MY RAMDISK" -d /boot/initrd.img-`uname -r` /mnt/uInitrd

by fixing i mean making the boot errors disappear, but unfortunately g_multi is still the one and only module i can get started
it seems like modules are started.. but something else is broken
bluetooth, wifi and my 3g usb modem are affected (wont work)...

i also found this message...
mount: mounting udev on /dev failed: No such device

let me know if you are experiencing something similar..
thanx!

'kay a little update (newbies like me might find it interesting)

ive found a bug report that helped me get cg2900's operations working!

https://bugs.launchpad.net/linaro-android/+bug/1002289

the error code was something like this:

Code: Select all

[ 656.452606] cg2900-btacl cg2900-btacl.0: CG2900 init failed

there were some others. they are all registered in the bug report!

i changed the files in /lib/firmware from CG2900* to CG29XX*

and just like that... wlanx and bluetooth are functional again...

unfortunately my usb 3G modem is still unavailable

any information/advice is, of course, welcome!

okay!

just to complete this post: i have installed hso drivers!
all my 6 ttyHSx devices are there...
context: i am using linaro ubuntu 12.05; kernel 3.4.0 (from git site)

i had to modify the kconfig file in my source folder... i used menuconfig... (xconfig also)
this creates a new .config file that should be included when compiling the kernel...
it means that it was unnecessary to install drivers... kernel 3.4.0 actually supports hso devices... you just need to configure it in order to include those drivers before building...

it was not easy to realize that... but in fact it was a pretty simple fix.
then, how did anyone mention it? i know you guys are busy but... cmon it took me 2 minutes

anyhow, i hope to help somebody with this

oh and by the way: the modem is not fully functional... i guess it demands too much current... (since ac adapter is shared because of the HW patch) i will try with a stronger power source...
