Is there a test for USB 2.0 vs. USB 1.1?
I am considering getting an external hard drive (once I save up enough $$$). My computer has two USB hubs, both operated by Intel 82820 815e (Camino 2) Chipsets. Since Intel came out with the chipsets about the same time USB 2.0 came out, I suspect that they are probably USB 1.1, but my Mandriva Linux Control Panel gives me no indication of whether they are USB 1.1 or USB 2.0. How can I be sure BEFORE connecting an external drive? Is there some app that can test for that? :scratch:
Thanks. Andy |

1) Run /sbin/lspci Code:
bash-3.1$ /sbin/lspci USB1 are either UHCI or OHCI. Since you mention intel chipset then it is UHCI. USB2 controllers have USB1.1 "translators" that is why you also see UHCI in my output. So, in other words, if you only see UHCI you have USB1.1 and if you see both UHCI and EHCI you have USB2. 2) Run dmesg Code:
bash-3.1$ dmesg |grep HCI |
