Modem [0703]: Motorola SM56 Data Fax Modem [1057:3052] (rev 04)
Sembrerebbe che trattandosi di winmodem non funzionerà mai sotto Linux e che c'è qualcuno che ha provato a scrivere i driver ma è rischioso usarli
Some quixotic souls are finding ways to run sundry winmodem chipsets under Linux:
PC-TEL "HSP" (PCI) chips: proprietary binary driver
Agere/Lucent/AT&T "LT" aka Apollo (ISA) and Mars/Venus (PCI) chips: often thrown in as a cheapo, no-name OEM part by IBM, HP, Dell, Gateway, Compaq, and others: proprietary binary driver
Agere/Lucent/AT&T "LT" aka Apollo (ISA) and Mars/Venus (PCI) chips: open-source driver (but not functional, yet). Please note that the Agere/Lucent AMR chipset is not compatible and not supported.
Motorola SM56 chips: proprietary binary driver and kludged fix for some recent kernels
Intel Modem Silicon Operation (formerly Ambient Technology, formerly a division of Cirrus Logic) "HaM" MD563X chipsets (with MD5628 DSP) only: proprietary binary driver
Ambient Technology (later bought by Intel, and formerly a division of Cirrus Logic) CL-MD5620DT chips: open-source driver
IBM "MWave" ACP chips: open-source driver
Conexant (Rockwell) HSF and HCF chips: proprietary binary drivers — which are now not only proprietary but also cost money if you want one that's not deliberately crippled; the last free-of-charge one is here.
Conexant (Rockwell) HSF chips (HCF not supported), kinda-sorta works without error-correction or data-compression if you disable RPI functions: proprietary binary driver
ESS ES56T-PI, ES56-PI, and ES56V-PI (PCI) TeleDrive chipsets (with ES2898S DSP chip): proprietary binary driver
ESS ES56V-I, ES56-I and ES56T-I (ISA) TeleDrive chipsets (with ES2890S DSP chip): proprietary binary driver
SmartLink (formerly ST Micro) SmartPCI56/561/562/563, SmartUSB56, and HAMR5600 chipsets: proprietary binary driver
Do "lspci -vv" and "lspci -n", while logged in as the root user, to list all PCI devices in hopes of identifying your PCI winmodem chipset, if that's what you have. ("cat /proc/pci" is also useful.) For PnP ISA devices, try "/sbin/pnpdump". Then, check Rob Clark's databases (1, 2) and linmodems.org. to see if you're in luck or not.
Binary-only drivers are very bad news, and should be shunned. (They're typically buggy for lack of peer review, poorly maintained, not portable to newer or different CPU architectures, prone to breakage with routine kernel or other system upgrades, etc.) Besides, you're still trying to make a silk purse from a sow's ear. Pursue this path, if you absolutely must justify your US $30 mistake, but You Were Warned.
What about USB-bus modems? Alas, almost all have turned out to be winmodems. Again, your best bet is to consult Rob Clark's databases (1, 2) and linmodems.org.
