Hi All,
I have installed *Debian 6.0 "squeeze" **64 Bit* OS on my PC with
default Linux Kernel *2.6.32* to test my usb application and driver on
my USB Development Board.
I have tried to connect that board on *USB 2.0 Port* which is
working fine without any issue regarding detection or enumeration. But,
Whenever I have tried to connect same USB device on *USB 3.0 Port* at
that time USB Device has been enumerated and detected as USB 2.0 Device
not USB 3.0 Device.
Please find following dmesg and lsmod output for more information.
#dmesg
[ 945.271232] usb 3-1.2: new high speed USB device using
ehci_hcd and address 4
#lsmod | grep xhci
usbcore 123175 4 usbhid,ehci_hcd,xhci
I have also attached complete log file which contains output of
Linux command like lsmod, lspci etc. for more information.
*Is there any issue regarding older kernel (2.6.32) which is not going
to support xhci host controller driver support for USB 3.0 device or any
issue regarding older Debian 6.0 OS?*
Please let me know your valuable feedback on this as soon as possible.
Thanks for your support.
