Since wikidot doesn't allow me to paste logs (claims they are links?) Here's shorter description of the problem.
Huawei E353 doesn't seem to be yet supported by either Shibby or Toastman (I'd humbly ask for it to be otherwise) (the two 3G builds). Even so, I managed to conjure cosmic Newbie powers to formulate this:
usb_modeswitch -v 0x12d1 -p 0x1f01 -V 0x12d1 -P 0x14db -s 20 -M "55534243123456780000000000000a11062000000000000100000000000000"
Yet, internet eludes me even though it works when connecting the dongle directly to computer (14dBi directional antenna taking care of signal). Here's a log snippet:
