I have used USB CFA-635 for a while without problems on a Advantec PCI CPU-card P-III
w/VGA/82562/Audio/C socket 370 815E
PCI-6870F-
Intel 1,2 GHz Pentium III, Tualatin, 512Mb PC
On the PC we also have a PCI-1603 2port RS232/Curentloop
PCI card
We have nopw switch the main board to a
Advantec PCI CPU-card SlotPC, w/LAN/VGA/LVDS/CFC
PCI-6881F-S0A1
Intel 1,1 GHz PentiumM,
SODIMM 512Mb PC2700
(still with the same Current loop card).
In both cases the OS is Win2000
When the USB drivers (cf-usb-2154b.exe) are installed on the new board the leds are only flashing and we can see some patterns on the LCD display, but its not possible to access the display (also tested with CrystalFonz test program). When this happens we are not able to open the Current Loop COM port (COM3/COM4) even if CrystalFontz COM ports are set to COM6/COM7 (and also tested with COM11/COM12).
This seems to be an IRQ conflict or a base address conflict.
