Hi,

Recently got my dialup server up and running and I was going through my PC collection testing modems when I stumbled upon an driver issue on my LION sarasota 8050i (looks to be an rebadged TINY 8050i). Originally I put SM56 drivers on there, which resulted in blank error popups from the SM56 helper when trying to do anything related with the modem (going into modem properties, trying to use hyperterminal) or

Incompatible modem codec detected, please check your modem card

errors.
Then I installed AGERE AC' 97 modem drivers and that "seemed" to fix the issue, although now I still get auto disconnected right after I press dial and I get

Cannot open COM5. Check port settings

error when I try to open COM port where the modem is. An HSP 56k modem driver results in an code 10 in devmgmt.

Now I am quite stuck here, the PCI\VEN_8086&DEV_24C6&SUBSYS_80511071&REV_03 doesn't give a lot of results. Some say on the TINY 8050i the SM56 drivers worked but on mine they don't.

Any ideas?

Hmm the .inf in Agere modem driver 2.1.38 for Tiny 8050 does list PCI\VEN_8086&DEV_24C6&SUBSYS_80511071 ;8050D
Maybe some leftover reg entry from the SM56 driver is causing it ?

May I know how to completely remove the SM56 modems? The uninstaller most of the time does absolutely nothing.
On the other hand Snappy driver installer detects the modem as an SM56, but I still get the same errors as before.

The SM56 drivers appear to add reg entries to HKEY_LOCAL_MACHINE\Software\Motorola\, check if there is anything left like HKEY_LOCAL_MACHINE\Software\Motorola\SMSERIAL\CurrentVersion\some number.
Also check if a file like SmSerial.sys is still in \system32 or \system32\drivers and check Task Manager to see if there is a "smserial" service running.

Removed every single registry mention of motorola, all the SM files from system32 and subfolders, double checked if SMHELPER or similar was running (only agere was running), tried safemode with networking (complained that the modem is missing) but still, same issue....
