ST7554: fifo underrun!


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:

hello spriggan,

i have a friend who is having the same problem...

i know you never received a reply here, but we are wondering if perhaps you were able to find a solution on your own...

if so, could you please share it with us??

anything you could tell us would be greatly appreciated...

thanks...

Hey win32sux

I was never able to solve this damn problem. I ended up throwing the modem away and getting myself a standard serial external one

Sorry I couldn't be of much help
