Hi patrikg,
Thanks again for the help, I've had a bit of a breakthrough!
I was able to get a WinXP executable called "PSCP.exe" (which I think is based on, or uses PUTTY behind the scenes) to work, just had to create the ssh config files ahead of time, start up openssh on TC 3.8.4, with a copy of "PSCP.exe" in a directory on an external hard drive, can type the usual;
pscp tc@172.16.1.98:/home/tc/data/* .
To copy the contents of the data folder on the CF card into the directory from which the PSCP.exe command was executed, somehow the PSCP.exe program deals with the
key issue, just allows me to accept the key from TC, and can continue on.
I got this "PSCP.exe" executable with a BeagleBone Black based data acqusition system, which is used to transfer data to/from the BBB.
With that, I was getting about 5-7 MB/sec over the 100 MBit ethernet port (onto an NTFS formatted external HD), but I noticed my "go-to" 64 GB FAT32 formatted pen drive was still stuck at around 1 MB/sec, which is also what I was getting with it when it was connected to the VortexDX3 USB ports as well, so that pen drive itself seemed to be the issue actually.
So, I tried some other pen drives connected direct to the USB 2.0 ports on the VortexDX3 and my goodness, what a difference!, can't believe it!, my 4 GB Cactus pen drive (ext4) was seeing almost 40 MB/sec and another mini 128 GB FAT32 formatted pen drive was getting 20 MB/sec!!, wow.
So all my problems with slow data transfers before was just due to using a low quality pen drive it seems!, wow, never expected that there could be such a difference.
Now that I know that the USB2.0 ports can indeed work pretty fast as long as you have a decent pen drive, this takes the heat off scp, etc., but at least I do have a viable "plan-B" with the WinXP laptop running "PSCP.exe" to transfer data onto an external HD, that works pretty well too but is a bit slower at 5 MB/sec.
Thanks again for the help,
David
