Hi,

 

I have bought Huawei E156 HSDPA 3G data card (USB stick ). Checked interenet connectivity with laptop (Windows) I am able to browse internet. I would like to test this with BF527 ezkit and before that I would like to know that is there any drivers available for this E156 HSDPA  3G data card in uClinux? or any drivers availabe similar to these kind of products in uClinux?

 

Thanks in advance.

First step is always to make it work with your Linux Desktop. If it doesn't work there - it isn't likely to work anywhere else.

Thank you very much. I tried by connecting data card to linux PC ( Suse 11.1). The linux PC can't able show atleast as USB device. But if I put  lsusb it shows " Bus 001 Device 011: ID 12d1:1003 Huawei Technologies Co., Ltd. E220 HSDPA Modem / E270 HSDPA/HSUPA Modem "

 

Are there any similar kind of 3G modules supported by bfin uClinux or uClinux?

we dont do anything special wrt modems in the kernel you get from this site.  any drivers it has are going to the be same as linux on your desktop.  we dont write drivers for any modems, nor do we really keep track of what modem drivers other people have written.

 

so either it presents itself as a standard acm device and so you get something like /dev/ttyACM0 or /dev/ttyUSB0 which you can program yourself using ppp, or it doesnt.

Have a look in the kernel source - there are a few 3G USB cards which are supported. But I can't answer any questions on them - we didn't write them, and don't support them.

 

If it works on your desktop - it will work on the Blackfin -- getting it to work on the desktop is up to you.

When I say  "Have a look in the kernel source", I mean "_you_ go look in the kernel source". I can't be responsible for you buying something that appears to have a driver, and then it doesn't work. You need to make the selection yourself.

 

Most (but not all) are in ./drivers/usb/serial/ - just look at the Kconfig.
