Hi list, I've noticed a strange USB disconnect of an external HDD. There's several USB devices connected to this machine at all times, mostly hubs, but some directly connected HDD gets hit by this issue.
It's reproducable under normal usage; tho I'm not sure what triggers it. It has happened both while accessing the HDD and during idle times. For what it matters, I replaced the HDD enclosure of a cypress chipset with a genesys logic one... doesn't matter. 2.6.23-rcX (this one is rc7) dmesg output: hub 1-0:1.0: state 7 ports 8 chg 0000 evt 0010 ehci_hcd 0000:00:02.2: GetStatus port 4 status 001002 POWER sig=se0 CSC hub 1-0:1.0: port 4, status 0100, change 0001, 12 Mb/s usb 1-4: USB disconnect, address 3 usb 1-4: unregistering device usb 1-4: usb_disable_device nuking all URBs usb 1-4: unregistering interface 1-4:1.0 usb_endpoint usbdev1.3_ep02: ep_device_release called for usbdev1.3_ep02 usb_endpoint usbdev1.3_ep86: ep_device_release called for usbdev1.3_ep86 usb 1-4:1.0: uevent usb 1-4:1.0: uevent usb_endpoint usbdev1.3_ep00: ep_device_release called for usbdev1.3_ep00 usb 1-4: uevent ehci_hcd 0000:00:02.2: GetStatus port 4 status 001803 POWER sig=j CSC CONNECT hub 1-0:1.0: debounce: port 4: total 100ms stable 100ms status 0x501 ehci_hcd 0000:00:02.2: port 4 high speed ehci_hcd 0000:00:02.2: GetStatus port 4 status 001005 POWER sig=se0 PE CONNECT usb 1-4: new high speed USB device using ehci_hcd and address 6 ehci_hcd 0000:00:02.2: port 4 high speed ehci_hcd 0000:00:02.2: GetStatus port 4 status 001005 POWER sig=se0 PE CONNECT usb 1-4: default language 0x0409 usb 1-4: new device strings: Mfr=56, Product=78, SerialNumber=100 usb 1-4: Product: USB2.0 Storage Device usb 1-4: Manufacturer: Cypress Semiconductor usb 1-4: SerialNumber: DEF107679C83 usb 1-4: uevent usb 1-4: usb_probe_device usb 1-4: configuration #1 chosen from 1 choice usb 1-4: adding 1-4:1.0 (config #1, interface 0) usb 1-4:1.0: uevent usb 1-4:1.0: uevent usb-storage 1-4:1.0: usb_probe_interface usb-storage 1-4:1.0: usb_probe_interface -
