I can give you at least one reference (the manufacture's tech. specs):


(page 5)

– SV92U2: USB 2.0 device controller, 48-pin TQFP Stack Bus


OS support: Win98SE/2000/ME, WinXP, WinXP 64-bit, Vista (Native Support), 
and Linux

If that is indeed your device, don't give up so easily :-) Just try with 
"sl-modem" drivers or ask LSI/Agere for advice, it could work.

When it comes to modems and linux, the only way to hit the right device 
is by using a RS-232 modem. No drivers needed and straight-forward setup 
for all kind of services (dial-up connection, fax facility...).

Yes, yes... I know. Serial port is a scarce resource in modern 
motherboards and n[eo]tbook computers ;-(
