Just tested on my (almost as old) laptop with Intel ICH9 EHCI controllers (GM45 chipset): bjorn@nemi:/tmp$ lspci -nns 00:1d.7 00:1d.7 USB controller [0c03]: Intel Corporation 82801I (ICH9 Family) USB2 EHCI Controller #1 [8086:293a] (rev 03) and it was a "success": [59091.240771] driver: '4-1:1.0': driver_bound: bound to device 'usbfs' [59091.339847] ehci-pci 0000:00:1d.7: EHCI hardware bug detected: 82008d80 00008d00 [59091.470486] ehci-pci 0000:00:1d.7: EHCI hardware bug detected: 82008d80 00008d00 [59091.535738] ehci-pci 0000:00:1d.7: EHCI hardware bug detected: 82008d80 00008d00 [59091.559874] ehci-pci 0000:00:1d.7: EHCI hardware bug detected: 82008d80 00008d00 [59091.567118] ehci-pci 0000:00:1d.7: EHCI hardware bug detected: 02008d80 80008d00 [59091.588250] ehci-pci 0000:00:1d.7: EHCI hardware bug detected: 82008d80 00008d00 [59091.590246] ehci-pci 0000:00:1d.7: EHCI hardware bug detected: 82008d80 00008d00 [59091.597376] ehci-pci 0000:00:1d.7: EHCI hardware bug detected: 02008d80 80008d00 [59091.604376] ehci-pci 0000:00:1d.7: EHCI hardware bug detected: 82008d80 00008d00 [59091.617502] ehci-pci 0000:00:1d.7: EHCI hardware bug detected: 82008d80 00008d00 [59091.619749] ehci-pci 0000:00:1d.7: EHCI hardware bug detected: 82008d80 00008d00 [59091.632002] ehci-pci 0000:00:1d.7: EHCI hardware bug detected: 02008d80 80008d00 [59091.649004] ehci-pci 0000:00:1d.7: EHCI hardware bug detected: 82008d80 00008d00 [59091.659503] ehci-pci 0000:00:1d.7: EHCI hardware bug detected: 82008d80 00008d00 So I guess this bug is common, at least in older Intel chipsets.
