Hi,
Me and my friend had been trying to connect to the net on Linux using a Reliance LG 2030 and Silicon Labs USB Cable ( the culprit!!!). Finally after 2 months of hard work, internet surfing and several linux compilations later, we finally found the solution. Any one else having the same problem, can refer to the following:
We used Knoppix Linux 3.9 with kernel version 2.6.12.2.
1) Download 2.6.x kernel source and untar it.
2) In the kernel source directory, do "make menuconfig"
3) Under USB devices, select USB serial support sub heading. In this, select the CP2101 driver as module. Also select the USB serial support.
4) Do "make","make modules", "make modules_install", "make install".
5) Modify the grub to boot to new kernel.
6) Reboot into new kernel.
7) Do "modprobe usbserial" and " modprobe cp2101" as root.
8) Run the wvdialconf script available on the net.
9) Get connected and Njoy!!!
