Don't worry, before getting into more technical details, below checklist may help you solve the easy problems:

1. Please connect your Perixx product to another PC/smartphone/tablet and check if the problem repeats. If it is a wireless product, please insert new batteries or ensure the product is fully charged. Then continue your test. Please try to connect your item to one of the USB ports on the back of your PC for a stable power connection, since the front USB ports do not provide enough power.
2. If the driver of the item doesn't work or doesn't recognize it. Please uninstall the driver, restart your PC, then download and install the latest driver from Perixx website:  (https://eu.perixx.com/pages/download-driver). Please also check your antivirus permissions right since it might block the execution of the hid.exe

Please don't hesitate to contact us if you have any further questions or comments.
