Some flash drives need to be formatted for the the device that you use it on.
the Mac you are using it on may not recognize the device and see it as incompatible.

After reading the description, I think you need to try updating BIOS and latest device drivers for USB. Because USB are getting power on that means there would not be any fault to from the motherboard.

So please try updating latest BIOS for your notebook.
If you can provide me the product no for your notebook and the operating system which you are using currently then I can find the one for you.

Otherwise you can also do the same.

Type in the product no. on www.hp.com. Then go to software and driver download page, select the proper OS and search in BIOS ROM pack available for your notebook.

I hope this will help.

Dont worry much about that, it's the way your PC recognises the device. you can rename the drive if you want in my computer

Insert the device and restart the computer. Does it shows a "removable disk" icon in My computer? If it does, go to the properties and click unblock, may it's block. If that doesn't work, then just reformat.

You mentioned that you uninstalled the unknown device from the Device manager. If you uninstall it then connected your usb flash drive you will see an error again on your device manager. This means that the driver for your usb port is not properly installed.

To install it, visit dell website, look for the model of your machine and locate the driver, download it then install from your machine.
