Yep, seems to be. What is echi_hcd? And is that something that will give me some talk-back, a la, dmesg, or does it just activate something?
Hi Peter,
Sorry for the typo... it's ehci_hcd, not echi_hcd.
From http://en.wikipedia.org/wiki/EHCI:
"The USB 2.0 HCD implementation is called the Extended Host Controller Interface (EHCI). Only EHCI can support high-speed transfers. Each EHCI controller contains four virtual HCD implementations to support Full Speed and Low Speed devices. The virtual HCD on Intel and Via EHCI controllers are UHCI. All other vendors use virtual OHCI controllers."
Just out of curiosity, what USB controller is listed when you run the following (as root):
00:1f.2 USB Controller: Intel Corporation 82801BA/BAM USB (Hub #1) (rev 05) (prog-if 00 [UHCI]) Subsystem: Toshiba America Info Systems: Unknown device ff00 Flags: bus master, medium devsel, latency 0, IRQ 5 I/O ports at 1820 [size=32] Pete -- Peter N.
