From: Yichong Chen Date: Wed, 17 Jun 2026 02:06:13 +0000 (+0800) Subject: usbip: tools: support SuperSpeedPlus devices X-Git-Tag: v7.2-rc3~5^2~24 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=195e667c8719480c320cd48ac0fbf1cb81d6ffe0;p=thirdparty%2Fkernel%2Flinux.git usbip: tools: support SuperSpeedPlus devices USB devices running at SuperSpeedPlus report "10000" or "20000" in their sysfs speed attribute. usbip currently maps only "5000" to USB_SPEED_SUPER, so a SuperSpeedPlus device is imported as USB_SPEED_UNKNOWN. The attach request is then rejected by vhci_hcd: vhci_hcd: Failed attach request for unsupported USB speed: UNKNOWN Map the SuperSpeedPlus sysfs speed values to USB_SPEED_SUPER_PLUS, use the SuperSpeed VHCI hub for SuperSpeedPlus devices, and recognize the gadget current_speed string used by the kernel.
