I'm using kernel 2.6.26-rc8. I do use CONFIG_USB_SUSPEND. If I attach USB disk (using EHCI driver), the disk is found and it is working. If I remove the disk, undock the laptop, dock the laptop again and plug the disk, the disk is not found at all until I remove and reinsert the EHCI driver. I noticed that if I do not unplug the disk berofe undocking, it works after docking back. If I undock with the disk removed, dmesg looks like this: [85164.642906] usb 3-4.3: USB disconnect, address 5 [85171.901891] ACPI: \_SB_.GDCK - undocking [85175.116094] eth0: Link is Down [85183.063339] ACPI: \_SB_.GDCK - docking [85185.238221] eth0: Link is Up 1000 Mbps Full Duplex, Flow Control: None nothing more past the eth0 message. If I undock with the disk plugged in, dmesg looks like this: [85407.425050] ACPI: \_SB_.GDCK - undocking [85407.453467] usb 3-4: USB disconnect, address 3 [85407.453478] usb 3-4.3: USB disconnect, address 4 [85410.870520] eth0: Link is Down [85420.340005] ACPI: \_SB_.GDCK - docking [85420.829661] usb 3-4: new high speed USB device using ehci_hcd and address 5 [85420.952520] usb 3-4: configuration #1 chosen from 1 choice [85420.960006] hub 3-4:1.0: USB hub found [85420.960006] hub 3-4:1.0: 4 ports detected [85421.066577] usb 3-4: New USB device found, idVendor=04b3, idProduct=4485 [85421.066583] usb 3-4: New USB device strings: Mfr=0, Product=0, SerialNumber=0 [85422.540557] eth0: Link is Up 1000 Mbps Full Duplex, Flow Control: None [85426.366908] usb 3-4.3: new high speed USB device using ehci_hcd and address 6 [85426.465420] usb 3-4.3: configuration #1 chosen from 1 choice [85426.485951] scsi9 : SCSI emulation for USB Mass Storage devices [85426.485966] usb-storage: device found at 6 [85426.485966] usb-storage: waiting for device to settle before scanning [85426.487217] usb 3-4.3: New USB device found, idVendor=152d, idProduct=2338 [85426.487217] usb 3-4.3: New USB device strings: Mfr=1, Product=2, SerialNumber=5 [85426.487217] usb 3-4.3: Product: USB to ATA/ATAPI Bridge [85426.487217] usb 3-4.3: Manufacturer: JMicron [85426.487217] usb 3-4.3: SerialNumber: 222291142391 [85431.482899] usb-storage: device scan complete any ideas? -- Luk??
