USB 3

[Ossy10]

I recently installed a PCle-U304BG.V2 USB3 card to my desktop computer and all appeared to work well with the exception of my HP LaserJet printer which slowed down to a crawl. I removed the USB3 card and everything and the printer was back up to its original speed. Is this possibly caused by the printer being old, as is the computer, and is there some way in which one of the USB ports could be programmed to act as USB 2 and not USB 3.
The details of the computer are

when you installed the new USB3 card, are you leaving the LaserJet still plugged into a USB2 port?
or is the printer that old that it uses a serial port?
after the new USB3 card was installed, did you try reinstalling the HP driver?

[Ossy10]

I am leaving the printer plugged into the original USB2 port on the computer and I re-installed the HP printer driver which I downloaded from the HP website

[Bruce]

as you may know, USB3 is backwards compatible, so plug in a USB2 device and it ‘will just work’.
can’t explain why the HP printer suddenly goes slow when the new USB3 card is installed and the printer still remains in its USB2 port.

as an exercise, did you try plugging the printer into the new USB3 port?

[Ossy10]

Yes I tried the printer on an USB3 port as soon as I installed the card I am now wondering if the card might be faulty although when I download to an external hard drive it does so at a much faster rate then the USB2 port used to do.

[Bruce]

could be a faulty card, but more likely the new card may not be 100% compatible with the old Foxconn motherboard. or yes, it’s just the old HP printer, especially if nothing else is adversely affected.

did you try using the drivers for the PCIe card? - shouldn’t need to as you have Win10 and the card should use the native USB3 driver, but worth a shot.

@Ossy10 - any progress?

[Ossy10]

I have not had any success so far as I didn’t receive any info about drivers with the card it just stated that with Windows 10 I didn’t need any. But I was speaking to a neighbour and he said that it could be the fact that I updated from Windows 7 to Windows 10 and that there could have been a blip in the update which wasn’t obvious at the time. So at the moment I am trying to find a driver for the card that I could download and install.

[Bruce]

definitely a good path to go down, keep us posted. (y)
