UD22 USB problems
Inspiron 14 Plus 7420
I have an Inspiron 14 Plus 7420 along with a UD22 dock.
I am experiencing issues where after going to sleep the USB ports in the UD22 dock are not responsive. The only way to fix this is to power the dock on and off. Taking the USB item out and reinserting doesn't work.
I've updated the latest firmware, all updates on my laptop. USB selective setting off, can't figure it out. Tried multiple USB products.
Display ports work fine on the dock, it's just the issues with the USB ports in the back.
Any ideas?

Always include version of Windows in your posts...
Open Device Manager and expand the list under USB. Double-click each USB device listed and if it has a Power Management tab, uncheck the box "Allow PC to turn off...". Repeat for all USB devices and then for all Human Interface Devices listed in DM that have a Power Management tab. Then exit DM.
Next, on same screen where you disabled USB Selective Suspend, disable Hybrid Sleep and PCI Express Link State Management.
Be sure to save the changes to the Power plan and reboot. Does that help?
