I came across my friend’s laptop during last week and I observe that when I connected my pen dive to his old HP laptop, the mouse sticks for a while. I mean I can see that mouse will not operate for couple of seconds. Since this was observed even after repetitions i thought there is some issue in the laptop USB controller. I still have to check by connecting other pen drives. I will update once I do this exercise again. My early question is, how does a low performance pen drive affect the functionality of other USB devices? What if the other device connected is very critical? Has anybody already observed this issue somewhere?
Issue between pen drive and mouse
When you connect a USB flash drive or pen drive on your computer, the machine doesn’t classify it as low performance or high performance device. All USB devices are the same because every USB device operates according to the USB port’s specifications. If one port is connected with a low-performing device and another port has a high-performing USB device, there will never be a conflict between their performances.
They will both operate and function according to the USB ports’ specifications. If one device is connected to a USB 2.0 port, it will operate according to the USB 2.0 specification. If the other device is connected to a USB 3.0 port, it will also operate according to the USB 3.0 specification.
Also, since the USB 3.0 specification is much faster than the USB 2.0 standard, transferring data will be much quicker compared to the other one.
