I'm sorry if this is a little late, but I had once had access to a Z6 and believe I had it successfully connected to my Linux host, and was therefore puzzled by this message exchange.
I have now borrowed the device again for the weekend to check it out a little more. Using Alan's patch below, otherwise my kernel is a standard 2.6.23-rc5 (CONFIG_USB_STORAGE_DEBUG=y ) I got the following result after reboot and connecting the Z6.: ohci_hcd 0000:00:02.0: auto-wakeup root hub hub 1-0:1.0: state 7 ports 3 chg 0000 evt 0002 ohci_hcd 0000:00:02.0: GetStatus roothub.portstatus [0] = 0x00010101 CSC PPS CCS hub 1-0:1.0: port 1, status 0101, change 0001, 12 Mb/s hub 1-0:1.0: debounce: port 1: total 100ms stable 100ms status 0x101 ohci_hcd 0000:00:02.0: GetStatus roothub.portstatus [0] = 0x00100103 PRSC PPS PES CCS usb 1-1: new full speed USB device using ohci_hcd and address 2 ohci_hcd 0000:00:02.0: GetStatus roothub.portstatus [0] = 0x00100103 PRSC PPS PES CCS usb 1-1: default language 0x0409 usb 1-1: new device strings: Mfr=3, Product=2, SerialNumber=4 usb 1-1: Product: MS usb 1-1: Manufacturer: Motorola Inc. usb 1-1: SerialNumber: 9013555524BA0C2005 usb 1-1: uevent usb 1-1: usb_probe_device usb 1-1: configuration #1 chosen from 1 choice usb 1-1: adding 1-1:1.0 (config #1, interface 0) usb 1-1:1.0: uevent usb 1-1:1.0: uevent usb-storage 1-1:1.0: usb_probe_interface usb-storage 1-1:1.0: usb_probe_interface - got id usb-storage: USB Mass Storage device detected usb-storage: -- associate_dev usb-storage: Vendor: 0x22b8, Product: 0x6426, Revision: 0x0101 usb-storage: Interface Subclass: 0x06, Protocol: 0x50 usb-storage: Transport: Bulk usb-storage: Protocol: Transparent SCSI scsi0 : SCSI emulation for USB Mass Storage devices usb-storage: *** thread sleeping. usb-storage: device found at 2 usb-storage: waiting for device to settle before scanning drivers/usb/core/inode.c: creating file '002' hub 1-0:1.0: state 7 ports 3 chg 0000 evt 0002 usb-storage: usb_stor_control_msg: rq=fe rqtype=a1 value=0000 index=00 len=1 usb-storage: GetMaxLUN command result is 1, data is 1 usb-storage: queuecommand called usb-storage: *** thread awakened. usb-storage: Command INQUIRY (6 bytes) usb-storage: 12 00 00 00 24 00 usb-storage: Bulk Command S 0x43425355 T 0x1 L 36 F 128 Trg 0 LUN 0 CL 6 usb-storage: usb_stor_bulk_transfer_buf: xfer 31 bytes usb-storage: Status code 0; transferred 31/31 usb-storage: -- transfer complete usb-storage: Bulk command transfer result=0 usb-storage: usb_stor_bulk_transfer_sglist: xfer 36 bytes, 1 entries usb-storage: Status code 0; transferred 36/36 usb-storage: -- transfer complete usb-storage: Bulk data transfer result 0x0 usb-storage: Attempting to get CSW... usb-storage: usb_stor_bulk_transfer_buf: xfer 13 bytes usb-storage: Status code 0; transferred 13/13 usb-storage: -- transfer complete usb-storage: Bulk status result = 0 usb-storage: Bulk Status S 0x53425355 T 0x1 R 0 Stat 0x0 usb-storage: scsi cmd done, result=0x0 usb-storage: *** thread sleeping. scsi 0:0:0:0: Direct-Access Motorola MSnc.

I can't see how Motorola could break it so badly that the USB connection now doesn't work with a PC running Linux? And you say that this seems to be a more widespread problem with Motorola devices? Do you remember which ones, and do they run Linux as well? The following is from connecting a Z3 that supposedly isn't based on Linux, but works all right (and this may have been the one I thought was the Z6 that I claimed worked): ohci_hcd 0000:00:02.0: auto-wakeup root hub hub 1-0:1.0: state 7 ports 3 chg 0000 evt 0002 ohci_hcd 0000:00:02.0: GetStatus roothub.portstatus [0] = 0x00010101 CSC PPS CCS hub 1-0:1.0: port 1, status 0101, change 0001, 12 Mb/s hub 1-0:1.0: debounce: port 1: total 100ms stable 100ms status 0x101 ohci_hcd 0000:00:02.0: GetStatus roothub.portstatus [0] = 0x00100103 PRSC PPS PES CCS usb 1-1: new full speed USB device using ohci_hcd and address 5 ohci_hcd 0000:00:02.0: GetStatus roothub.portstatus [0] = 0x00100103 PRSC PPS PES CCS usb 1-1: ep0 maxpacket = 8 usb 1-1: default language 0x0409 usb 1-1: new device strings: Mfr=1, Product=2, SerialNumber=3 usb 1-1: Product: Motorola Phone (Z3) usb 1-1: Manufacturer: Motorola Inc. usb 1-1: SerialNumber: 00440102299883 usb 1-1: uevent usb 1-1: usb_probe_device usb 1-1: configuration #1 chosen from 1 choice usb 1-1: adding 1-1:1.0 (config #1, interface 0) usb 1-1:1.0: uevent usb 1-1:1.0: uevent usb-storage 1-1:1.0: usb_probe_interface usb-storage 1-1:1.0: usb_probe_interface - got id usb-storage: USB Mass Storage device detected usb-storage: -- associate_dev usb-storage: Vendor: 0x22b8, Product: 0x4810, Revision: 0x0002 usb-storage: Interface Subclass: 0x06, Protocol: 0x50 usb-storage: Transport: Bulk usb-storage: Protocol: Transparent SCSI scsi3 : SCSI emulation for USB Mass Storage devices usb-storage: *** thread sleeping. usb-storage: device found at 5 usb-storage: waiting for device to settle before scanning drivers/usb/core/inode.c: creating file '005' hub 1-0:1.0: state 7 ports 3 chg 0000 evt 0002 usb-storage: usb_stor_control_msg: rq=fe rqtype=a1 value=0000 index=00 len=1 usb-storage: GetMaxLUN command result is 1, data is 0 usb-storage: queuecommand called usb-storage: *** thread awakened. usb-storage: Command INQUIRY (6 bytes) usb-storage: 12 00 00 00 24 00 usb-storage: Bulk Command S 0x43425355 T 0x1 L 36 F 128 Trg 0 LUN 0 CL 6 usb-storage: usb_stor_bulk_transfer_buf: xfer 31 bytes usb-storage: Status code 0;
