With the VegaComb 3.2 Build 9n Update 3 on a Viewpad 10s, the Huwaei E1750 works flawless. Offcourse in USB Host mode.
I've tried also a ZTE MF-100 but that doesnt work. Seems like because its making 3 interfaces: modem, at, diag.

Thanks for the Tip, i got myself a Huawei K3765, disabled the USB storage mode on the modem with: AT^U2DIAG=0 comand from WinXp Hyperterminal and finally got internet connection working on VegaComb 3.2 Build9n out of the box.

Think i found a way...
After a lot of research i think found something what we could use to expand our P10AN devices with 3G and even some more gigabytes
The port where the webcam is connected inside the tablet is a simple usb port,
with a simple internal connector.
Yesterday i went to the local electro-store and bought one which is almost like the original, and fitting in to connector just fine.
After this i've disassembled my Huawei E1752 housing, put out the chip from it,
and desoldered the usb connector, replaced with the new one.
Working like charm, the only bad is that i've lost my camera, since there is no more free port. Maybe i can fix this in the future with a small usb hub, maybe...

Afterall if you set your modems AT^U2DiAG=256 then you will have a working 3G and SD Card reader.

Since i want to reconnect somehow the camera, i'm not going to assemble the tablet until that. But it seems like everything is going to fit in.
After finished with everything i will make a tutorial with images included.

If you want the camera working again then you have to use a hub yes...

I'm still trying to find the perfect one, which is fit into this small place.
If anybody could help me in that a little that would be great!

We need 2 port usb hub, which is square shaped and only 20x20mm.

Lightbulb Update on 3G mod
So here is a little update on the 3G mod for our vegas.

Measured a little inside the the device and seems like after
i have put in the 3g stick we have left exactly 25mm X 55mm space
for the usb hub, offcourse with the housing and connectors disassembled from it.

As it can see on the second picture the back of the tablet seems like
to fit nicely, there will be enough space for the stick.

On the last three pictures there is the connector what everybody need for the mod, but i haven't found yet it on international online stores.
So if somebody could find one please let me know!

One more important thing is, that the Huawei E1750 datasheet only mention sd card handling up to 4gb.
But it's not true, for me it can handle perfectly the 16gb sdhc card!

Any chance you could run a speed benchmark on the sdcard? I want to integrate a hub and twin sd cards for swap memory and a2sd but I need to know if the internal usb is usb2 and won't cause performance bottlenecks.

Hello everybody, I would like to thank all users to help us get over our problems more or less trivial.
I got a PoV Mobii Tegra with HUAWEI EM770W 3G, and ROM: VC 3.2 9n Update 3.2.5x2 Diet Edition Edited by Areo. | Kernel: [email protected] #7.
I tried 4 sim cards, from 4 different operators, but none worked.
What I need to do?
By the way, the tablet was from the factory with 3g modem in it.

2 photos inside the tablet:


I'm sorry for the bad english and bad expression.
Thanks!

Hi!

Unfortunately i cannot run benchmark for now, because two of my hubs stopped
working with the device. Also i think i will give up with the usb hub idea, because
found a similar thread on the Modaco forum and read the same hub problems there.
Anyway when i will have a little time later this week/maybe next i will resolder the
whole thing for just only 3G Stick without camera (since i almost never use it, not a big skype fan :P) and than i will post you some results.
Based on the kernel logs (dmesg) it seems like every USB is connected to the
same hub inside the device and these are USB2 (at least appears to).

As far as i know the EM770W should work with the custom roms.
Why are you using such an old roms? Try one of the newer HoneyIce roms,
maybe the RC3, but i recommend the RC2.1.
I've linked my archive on Tabletroms, there you can download it.
