Please forgive me if this has already been covered elsewhere, but I couldn’t find an exact match to my problem. When I try to install the Windows 8 driver, it starts to run but then comes up with the following message:
[color=#BF0080]Windows encountered a problem installing the driver software for your device
Windows found driver software for your device but encountered an error while attempting to install it.
PCSGU250 Oscilloscope/Function Generator
A problem was encountered while attempting to add the driver to the store.
If you know the manufacturer of your device, you can visit its website and check the support section for driver software.[/color]
I don’t believe that this is going to be cured by disabling the digital signatures (please correct me if I’m wrong), as this seems to have a specific error message.
[quote]I don’t believe that this is going to be cured by disabling the digital signatures (please correct me if I’m wrong), as this seems to have a specific error message.[/quote]Windows 8 requires that all drivers are digitally signed, but the PCSGU250 driver is not. To avoid this requirement, disable driver signature enforcement.
Please Google on how to do this, there is an abundance of instructions available
Thanks for that. I’ve finally got round to doing this and I have now managed to load the driver.
However, I’m now back with an old problem that I had on Windows XP from time to time. The computer recognises that the device is present, but on running PcLab2000LT, the scope fails to switch on. I have tried it out with and without a separately powered USB hub (which I was advised to get to solve this problem). I know that the scope does work, as it still runs on my old Windows XP machine (most of the time).
Any other ideas?
Do you see the text “Loading, please wait…” on the oscilloscope screen at the startup?
Or, do you get the “No hardware response!” message window displayed?
I do get the text “Loading, please wait…”, but then it fails to switch on. I have tried it many times now on both machines. It has worked every time on my old Windows XP computer, but never on my new Windows 8.1 one. As I say, I have tried with and without the powered USB hub, so I’m completely at a loss as to what to try next.
It seems this is the cause of the problem:
The current consumption increases after the firmware is uploaded to the PCSGU250 while the “Loading, please wait…” is displayed.
If the current consumption of the PCSGU250 is too high for the PC’s USB output, the PC disconnects this USB port.
It’s very strange the problem occurs also with the powered USB HUB.
Normally PCSGU250 takes about 27mA at the startup just when USB cable is plugged in.
When the PcLab2000LT program is running and firmware is uploaded, the current consumption increases to about >400mA.
This amount of current seems to be too high for your PC’s USB port and for the powered USB HUB.
Here seems to be an alternative solution:
I’m still having no luck with this. I’ve tried the link, but it makes no difference. The powered hub should be good for 2A and the scope is the only thing plugged into it. I also had the same problem many times with the scope on the old XP machine (that’s why I bought the powered USB hub). It does work on the old machine (but intermittently). It never works on the new machine. I’m beginning to think that there’s a fault on the scope.
