Hi again, meanwhile I did some debugging.
QuickPort dump_device_desc: http://pastebin.com/h62jLHui QuickPort dump_curr_config_desc: http://pastebin.com/6rheBiMi Debug messages (hw.usb.debug=4): http://paste2.org/p/1733421 I found an external HDD enclosure (Sharkoon Rapid-Case 3.5" SATA USB3.0) which uses the same SATA bridge chip (ASM1051, Vendor 0x174C, Product 0x55AA). Attached to an USB port it uses high speed instead of full speed of the QuickPort. Rapid-Case dump_device_desc: http://pastebin.com/B7suMZG7 Rapid-Case dump_curr_config_desc: http://pastebin.com/D6xPyYUp The only difference I could find is wMaxPacketSize in Endpoint 0 and Endpoint 1 is set to 0x40 for the QuickPort. The Rapid-Case external enclosure has set wMaxPacketSize to 0x200. Having a look at lsusb's output under Linux wMaxPacketSize is set to 0x200 even for the QuickPort: http://pastebin.com/fMcxhKax If more debug information is needed don't hesitate to ask. :-) Best regards Franz _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-usb To unsubscribe, send any mail to "freebsd-usb-unsubscr...@freebsd.org"
