Hi, I'm trying to use my Canon EOS 550D digital camera with kernel 2.6.32, it seems to be correctly recognized, but I see an USB disconnect after about 30 seconds. This is the relevant section of dmesg: [ 1205.408516] usb 1-1: new high speed USB device using ehci_hcd and address 3 [ 1205.541927] usb 1-1: New USB device found, idVendor=04a9, idProduct=31ea [ 1205.541931] usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [ 1205.541933] usb 1-1: Product: Canon Digital Camera [ 1205.541935] usb 1-1: Manufacturer: Canon Inc. [ 1205.542023] usb 1-1: configuration #1 chosen from 1 choice [ 1234.913526] usb 1-1: USB disconnect, address 3 Using lsusb during the 30 seconds it stays connected seems to give a reasonable answer: Bus 001 Device 003: ID 04a9:31ea Canon, Inc. I captured usbmon output during this phase and you can find attached to this email. I also tried with kernel 2.6.37-rc7 but I obtained the same results. Ciao Alessio
