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. -- Regards, Ritesh Prajapati, System Level Solutions (India) Pvt.Ltd. |
