We have a usb scanner that requires 500mA of power. However, for several of our customers using HPs, the usb ports are not providing enough power to the scanner causing an application crash. Some customers are using the HP EliteDesk 800 G1 USDT, others are using HP t310 zero clients. Plugging the scanner into a powered usb hub has resolved the issue every time.
Is there a modification they can make to the Universal Serial Bus Controllers to ensure that a particular port will be able to provide 500mA so they do not need to purchase a powered usb hub for every system? Or do you have another suggestion?
Thanks in advance.
