Good luck.

I did a factory reset and it updated to 2.50 and initially everything seemed fine. However when I tried to transfer a group of 22 files using Calibre it failed at some stage (I think most got transferred but not all). I then found that trying to copy a single 7Mb file without Calibre also failed. I've changed the USB settings as mentioned by tshering and still have problems but I now know it isn't Calibre driver related. My sqlite file is ~38Mb so yes this is going to be quite stressfull.
It's easy to forget that the Glo is not like a USB stick - a passive device, but relies on Linux on the Glo to expose the memory as a USB mass storage device (I'm assuming here it does work like my trusted Hanlin V3s).
It looks like I need to find a way to "downgrade" to 2.4.0 to check if the problem is actually upgrade related, though I may not be able to transfer the necessary files onto the Glo as that is 85Mb.
Incidentally I discovered that when I do a factory reset the Glo is initially seen as having a Product ID of 4163, it changes to 4173 once the upgrade is complete (presumably to whatever version is current, this explains the 4163 I have been seeing in the Registry. If you look at the following two entries from USBDeview :
You can see what is happening - the second entry is left over from before the factory reset and the first one (after the factory reset and before the on-line update is complete) is the "active" one at the time I took the snapshot (It's drawing 2mA which is how you can distinguish it).
This explains my earlier comment about the Product ID. It is more of a curiosity than anything else but could be of interest.
Once more thanks for the ideas - it has helped me focus on eliminating the initially confusing results I was seeing.
