I had an old 4 port pci Usb expansion card lying around that i recently installed on one of my computers in order to supplement the quantity of available usb ports in it.The box in which the card was contained states that it supports USB 2.0.Despite being rather old,the card was detected in windows 10 and was installed without a hitch;however when i attempted to connect a pen drive to one of its ports and copy some data from it to my HDD,the transfer speeds were pathetically slow-in the region of 700kb/s-1MB/s and therefore it was practically unusable! I tried a variety of pen drives but the results were still the same.Also when i tried to copy some data from my hdd to pen drive the speeds i got were even slower.
The usb ports that are built into my motherboard usually give much higher transfer speeds that vary from 10-20 MB/s,but i don't understand why this card gives such slow speeds even though its supposed to be usb 2.0 compliant.On checking device manager i found that it has been detected as "ULI usb 2.0 enhanced host controller"(check screenshot).Can anyone tell me why is it providing such slow speeds-is it a limitation of the card itself or is something else causing this issue?
