Please find attached a report of what I suspect to be a bug introduced in kernel 2.6.38 with USB drivers. The error message is coming from ehci_hcd. Thanks and regards, Richard Senior
1. Summary ---------- USB device fails to connect in 2.6.38 but was OK in 2.6.37 and prior 2. Description -------------- PC in question is a Toshiba Equium L350 laptop. Device in question is a Tascam DP-01FX Digital Analog Workstation (DAW) for recording audio. The latter has a USB interface for exporting WAV files that I've used successfully on Ubuntu versions up to 10.10 (kernel 2.6.35). After upgrade to 11.04 Alpha 3 (kernel 2.6.38), the device will not connect, although other USB devices, e.g. USB drives, work OK. I have confirmed that reverting to kernels 2.6.35, 2.6.36 and 2.6.37 on the same laptop results in a successful connection. On 2.6.38 Connection fails with the following messages when the USB cable is plugged in: Mar 15 09:45:25 calder kernel: [ 531.160150] usb 2-3: new high speed USB device using ehci_hcd and address 4 Mar 15 09:45:40 calder kernel: [ 546.280119] usb 2-3: device descriptor read/64, error -110 Mar 15 09:45:56 calder kernel: [ 561.510064] usb 2-3: device descriptor read/64, error -110 Mar 15 09:45:56 calder kernel: [ 561.740256] usb 2-3: new high speed USB device using ehci_hcd and address 5 Mar 15 09:46:11 calder kernel: [ 576.860079] usb 2-3: device descriptor read/64, error -110 Mar 15 09:46:26 calder kernel: [ 592.090099] usb 2-3: device descriptor read/64, error -110 Mar 15 09:46:26 calder kernel: [ 592.320142] usb 2-3: new high speed USB device using ehci_hcd and address 6 Mar 15 09:46:31 calder kernel: [ 597.350130] usb 2-3: device descriptor read/8, error -110 Mar 15 09:46:37 calder kernel: [ 602.480214] usb 2-3: device descriptor read/8, error -110 Mar 15 09:46:37 calder kernel: [ 602.710102] usb 2-3: new high speed USB device using ehci_hcd and address 7 Mar 15 09:46:42 calder kernel: [ 607.740223] usb 2-3: device descriptor read/8, error -110 3.
