I have made several attempts to reproduce this problem, but I have not seen this problem any more. I can't explain what happended the two times I did see a problem.

I have tried with a USB 2.0 controller. The DiMAGE A2 camera is USB 2.0 compliant, or atleast KonicaMinolta says so ;-). The patch does not help here since it modifies uhci-hcd. The camera is not reconized. ehci_hcd 0000:00:0b.2: GetStatus port 2 status 001803 POWER sig=j CSC CONNECT hub 1-0:1.0: port 2, status 0501, change 0001, 480 Mb/s hub 1-0:1.0: debounce: port 2: delay 100ms stable 4 status 0x501 hub 1-0:1.0: port 2 not reset yet, waiting 50ms ehci_hcd 0000:00:0b.2: port 2 high speed ehci_hcd 0000:00:0b.2: GetStatus port 2 status 001005 POWER sig=se0 PE CONNECT usb 1-2: new high speed USB device using address 2 usb 1-2: control timeout on ep0in ehci_hcd 0000:00:0b.2: devpath 2 ep0out 3strikes ehci_hcd 0000:00:0b.2: devpath 2 ep0out 3strikes usb 1-2: device not accepting address 2, error -71 hub 1-0:1.0: port 2 not reset yet, waiting 50ms ehci_hcd 0000:00:0b.2: port 2 high speed ehci_hcd 0000:00:0b.2: GetStatus port 2 status 001005 POWER sig=se0 PE CONNECT usb 1-2: new high speed USB device using address 3 usb 1-2: control timeout on ep0in ehci_hcd 0000:00:0b.2: devpath 2 ep0out 3strikes ehci_hcd 0000:00:0b.2: devpath 2 ep0out 3strikes usb 1-2: device not accepting address 3, error -71 ehci_hcd 0000:00:0b.2: GetStatus port 2 status 001002 POWER sig=se0 CSC hub 1-0:1.0: port 2, status 0100, change 0001, 12 Mb/s An interesting thing is that the DiMAGE A2 camera can be set to diffrent data transfer modes. USB Storage is what causes us problems and what we have been using here. But the camera kan also på set to PTP mode. In this mode the camera is allways reconized by Linux and I have not seen any problems (other then that I think PTP mode is more inconvient to use and slower compared to USB storage). Here is an example with PTP. ehci_hcd 0000:00:0b.2: GetStatus port 2 status 001803 POWER sig=j CSC CONNECT hub 1-0:1.0: port 2, status 0501, change 0001, 480 Mb/s hub 1-0:1.0: debounce: port 2: delay 100ms stable 4 status 0x501 hub 1-0:1.0: port 2 not reset yet, waiting 50ms ehci_hcd 0000:00:0b.2: port 2 high speed ehci_hcd 0000:00:0b.2: GetStatus port 2 status 001005 POWER sig=se0 PE CONNECT usb 1-2: new high speed USB device using address 2 usb 1-2: new device strings: Mfr=1, Product=2, SerialNumber=0 usb 1-2: default language 0x0409 usb 1-2: Product: DIMAGE CAMERA usb 1-2: Manufacturer: KONICA MINOLTA usb 1-2: hotplug usb 1-2: adding 1-2:1.0 (config #1, interface 0) usb 1-2:1.0: hotplug # cat /proc/bus/usb/devices T: Bus=04 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=12 MxCh= 2 B: Alloc= 0/900 us ( 0%), #Int= 0, #Iso= 0 D: Ver= 1.10 Cls=09(hub ) Sub=00 Prot=00 MxPS= 8 #Cfgs= 1 P: Vendor=0000 ProdID=0000 Rev= 2.06 S: Manufacturer=Linux 2.6.7 uhci_hcd S: Product=UHCI Host Controller S: SerialNumber=0000:00:07.2 C:* #Ifs= 1 Cfg#= 1 Atr=c0 MxPwr= 0mA I: If#= 0 Alt= 0 #EPs= 1 Cls=09(hub ) Sub=00 Prot=00 Driver=hub E: Ad=81(I) Atr=03(Int.)
