USB Serial problem / Promethean boards

[D0liver]

So currently our new windows 8 image has broken all of the Promethean boards (10 years old)

The quick fix is going to device manager and selecting to update the COM port to the 2011 driver and the boards works again. When the USB is unplugged it happens again...any ideas?

We use activinspire...is there a way to remove drivers from device manager? If it only had the driver to use if should work?

I have this issue of disconnects/shaky pens or on my site at the moment, as I have lots of Promethean boards on a mixture of Serial/Serial to USB and USB connections depending on the way they were setup before I started in role.

 

We have upgraded our site to Windows 7 64 bit here, during which I found that the USB to serial connectors aren't all compatible with 7 64 bit, the connectors suffer from having their chipsets updated or discontinued with certain versions of windows.

 

The drivers are also lacking for the Prolific (PL-2303) and Aten (UC232A) Serial to USB connectors and using them seem to be very flaky with the drivers with the problems already subscribed even with brand new chipset USB-Serial connectors. (There is now a decent looking new 1.10 driver for the prolific brand models which seems to be very solid regardless of the chipset now I am finding with my testing so far).

 

I have had also better success with problematic boards through changing them to a pure USB based cable instead of Serial/Serial to USB connector, I only have one board at the moment that I am monitoring now thankfully.

 

I have also found that the new 5.9 Activdriver software won't auto start any serial connection for us, even if we turn it to Automatic it doesnt seem to hold that for either Serial or Serial to USB, so we are using 5.7 on that particular one as a workaround.

anyway to remove drivers or find the drivers that are listed in Device Manager?
