Windows 10: wireless mouse and keyboard bluetooth USB device not recognized- The last USB device you...

I am trying to connect my wireless mouse and keyboard to my windows 11 laptop using a USB Bluetooth adapter I got with that wireless mouse and keyboard, and I am getting below error messages.The last USB device you connected to this computer malfunctioned and windows does not recognize it.Try reconnecting the device. If windows still does not recognize it, your device may not be working properly.

No USB devices recognized

Curious - were they wireless? I note many motherboards maintain +5V power to some or all USB ports so users can use the ports to charge USB devices (like cell phones) while the computer is in sleep mode. That charging voltage is at a higher current than needed for a wired keyboard or mouse. If disabled, there may not be enough current for a wireless dongle.

That said, most motherboards have designated USB ports just for the keyboard and mouse (often color coded in green and purple). I would think they would provide enough current for a wireless dongle since wireless keyboards and/or mice are so popular these days. At least on PCs. For notebooks, maintaining power to wireless dongles might drain the battery unexpectedly.

usb device not recognized

too many devices on the same usb hub, 1 usb hub can only give around 150mA to 1 device, but that device can negotiate to get 550mA, but in that case its sucking all the power that the specific USB hub can provide, usualy wifi and bluetooth will suck up 550mA, diabling the hub for more devices
