That was me. The interesting thing was that the hamlib rigctl program wor=

perfectly through the USB port, but XLOG/TLF/GRIG didn't.

XLOG would grind to a halt, and, from memory, TLF would become errattic w=

the QRG updates, complaining about time-outs. As a matter of interest: TL=

worked OK if I put a TNC on the USB port (for DX-Cluster spots), and have=

rig control on the serial port.

I had a look for time-out values using USBview, but couldn't see anything=

obvious. If memory serves me, there were references to 50 ms

Anyway, it is quite possible that these problems are due to the hardware.=

USB drivers stop talking to the USB hub built into my notebook, after a=20
random number of hours, and I have been unable to fix this.

I have gone back (from 2.4.20) to a 2.2.23 kernel, but the USB hassles=20
remain, which is a bummer, because my trusty notebook only has one serial=

For contesting, it's a toss-up between DX-Cluster and rig control support=
 :-(

I am toying with the idea of trying a PCMCIA RS232 card, if I can get my=20
hands on one.
