Hi There
I have a Mecer USB modem (smartUSB56) that i want to use to dial up. I have installed all the drivers from smlink dot com and have the same error with the stable 2.7.14 driver and the newest 2.9.6 driver. I can dial up perfectly using kppp but after a few minutes of usage the connect flatlines (no data transfer in or out). if I exit X and go to a console, the following error is streaming down my screen.
ST7554: fifo underrun!
I have no idea how to solve this problem having used both drivers? this is my hardware setup:
Shuttle SN45G - Nvidia nforce 2 ultra 400 chipset
AMD Athlon XP 2400+
Nvidia Geforce FX 5200 (Gainward)
I have also installed the newest nforce drivers from nvidia dot com. I am running Fedora Core 1. If a do a dmesg, this is the following output:
