Description Joel Carlson 2005-12-13 20:59:19 UTC 
With SUSE 10.1 A3 we can connect to the internet with our Best Data 56K USB dialup modem Model #56USBP but the speed is very slow- less than half of normal dialup speed. This needs to be fixed.
Comment 1 Stefan Hundhammer 2005-12-14 10:48:23 UTC 
What do I have to do with that?
Comment 2 Karsten Keil 2005-12-14 11:49:31 UTC 
Does it work better with previous SUSE Linux/other Linux versions ?
Please attach the hwinfo output.
Comment 3 Michael Gross 2005-12-14 12:38:17 UTC 
Joel: Please attach `hwinfo --modem'. What exactly appears to be the problem? Does it take a long time for the modem to actually dial or is it the handshake after the dial that takes so long? Are you sure the problem's source is not at the other end of the line?
Comment 4 Joel Carlson 2005-12-14 19:35:46 UTC 
We can connect OK. Dial & handdhake are reasonably normal. Problem not at other end. It is the data rate on SUSE 10.1 A3 that is very slow- less than half of normal. However this is the first time we could dial on the HP ZE2113US laptop. We could previously dial with USB modem on standard desktop with SUSE 9.3 & surf at normal rate.

Comment 9 Michael Gross 2005-12-19 17:40:50 UTC 
It's quite possible that you're using a closed source driver which is artificially limited in speed, I read about this certain times. Maby one of the people in the CC can give us a clue?
Comment 10 Forgotten User ZhJd0F0L3x 2005-12-19 20:04:13 UTC 
no, cdc-acm is the generic usb modem driver.
Comment 11 Karsten Keil 2005-12-19 22:02:14 UTC 
SO I think it maybe  a problem with a correct INIT string or the modem do not full fill the USB ACM specification. Please look at the HP manuals for the AT command reference and try some options.
We cannot do anything more without hardware.
