Bought a new card reader, its 3 micro SD slots, UHS II so should be quick and hopefully not break like all the $2-3 ones I have had over the years.

Anyway, plug it in and this happens.

So, I guess I need to add a USB PCIe card. Last trek down that path was a NEC based one which was no end of trouble, PC not suspending, devices not leaving device manager when unplugged and bluescreens on file copies.

So what is a good chipset to get on a PCIe USB card that people dont have problems with, in windows 7 64 bit.

Maybe first check with USBView to find an opportunity to disable any unused devices:

Page said to download the debugging tools, which I did but there is nothing called USB view included with it. Is that a 10 specific feature? This machine is still 7 because it lacks space to upgrade still.

Perhaps gzt is referring to USBDeview 2.51. It has cured many USB issues for me.

Enable disconnected devices first:
Options > Display disconnected devices

Select all (disconnected devices):
File > Uninstall Selected Devices.

I have done this many times. Windows will (should) reinstall the inserted USB device next time it is connected.

It may work for your issue.

NirSoft have many other tiny and useful freeware programs. I use many of them.

Interesting technical overview of the problem here:

One migration they suggest is essentially forcing some low speed devices to usb2 to free up the usb3 resources. +others

I selected everything that was disconnected and uninstalled it, and that also appeared to include the keyboard and mouse. Oops.

Anyway, unplugging and replugging them got it working again. But same thing still happens. Guess I can unplug printers or webcams to use the card reader, but as I accumulate more stuff this will just become more of a problem.

I think its mainly the gaming peripherals.

But also like the printer has 6 devices with its card readers and stuff, the label printer is similar with its fake CD rom with drivers, Ext HDD's have at least 2 with the WD SES device as well.

I dont have that much plugged into this machine, so it must really be a problem for people that own heaps of peripherals. I recall USB was promised to have 127 devices per port or something quite reasonable, im having issues with under 14.
