After having the issues with my previous laptop (and working for a storage company), I decided to get a USB 2.0 external hard drive to (regularly) backup all of my data. I chose a Maxtor USB 2.0 drive and it seemed to work fine for a few days, but I quickly ran into some issues. The MacBook Pro wouldn’t even mount the drive. I thought it was just the drive, so I went to the local CompUSA and bought a USB 2.0 enclosure and a Samsung 300GB drive. I had the exact same problem. When I did a ‘cat /var/log/system.log’, I could see various messages similar to this one:
May 16 23:16:14 XXX kernel[0]: USBF: 12462. 59 AppleUSBEHCI[0x36e2000]::DoIOTransfer – error 0xe000404f queueing request
I have filed a bug with Apple (#4550783) and they are currently investigating the ‘ioreg -l -w0′ output. If I switch and use a Firewire compatible enclosure, everything works great. Has anyone else had problems with this? I’ve heard this has been an ongoing issue, not anything specific to the MacBook Pro.

I see the same error with a MacBookPro but using the Apple USB modem. It drops the connection after about 2 minutes with the same error. Looks like there is something wrong with the USB subsystem.
I’m having the same problem with an external drive I use. It’s an Archos Multimedia Jukebox and it used to work just fine. But now it won’t even mount.
The dmesg output:
disk1s1: I/O error.
USBF: 469.936 AppleUSBOHCI[0x1512800]::CreateGeneralTransfer – trying to queue to a stalled pipe
USBF: 469.936 AppleUSBOHCI[0x1512800]::DoIOTransfer – error 0xe000404f queueing request
I’m still working with them on the bug. They’ve given me some files to load and try, but it appears they’re for 10.4.6. I’m in the process of trying to get new ones for 10.4.7….hopefully they can get this resolved quickly.
I’m having the same probably with a USB enclosure from CompUSA and a 250GB Maxtor, using them on a Macbook Pro. This enclosure has card readers and usb ports on the front, so I really don’t want to replace it. I’m going to try it on an iMac G5 at work today. Let me know if they get it working for you.
I’ve been tied up for the last few weeks — they’ve asked me to try it on 10.4.7. Hopefully I’ll get to it this weekend…I’d like to see them fix this and get it into future revisions of the OS.
I have the same errors with my USB-2 hub (sweex) that connects my mouse and keyboard to my mac-mini (G4). This seems to indicate that the problem is not restricted to USB hard drives.
Yeah, I would definitely suspect it’s not restricted to USB hard drives as it seems like it’s the complete USB subsystem altogether.
I have the same issue with a recently-installed USB 2.0 PCI card in my MDD dual G4 1.25GHz. I’m running 10.4.8.
My 5G iPod mounted and seemed to sync with iTunes, but iTunes was *very* hung (‘kill -9 pid’ didn’t even work). The rest of the machine was fine. This has happened twice now.
Same error:
USBF: 5716.877 AppleUSBUHCI[0x2dd6000]::DoIOTransfer – error 0xe000404f queueing request
The iPod sync works fine – though slowly – with the native USB (1.x) ports on the machine.
And everything is reported fine in System Profiler:USB High-Speed Bus:

With hope, your bug is addressed soon.
The bug is still in the OPEN state — bug id #4550783. I’ve given them the information they needed before 10.4.7…judging by the pre-10.4.9 notes, it’ll probably just be pushed out to 10.5….
Hi,
nothing new with the 10.4.9 version ??? I have the same problem with an external USB drive and I have the same problem with 10.4.8.
Nope – I actually moved to using Firewire for what I needed to do, but it doesn’t appear to be resolved yet. I’d bet it’ll just be punted to 10.5 — to me, it’s a very serious USB issue that needs to be resolved.
I am having the same issue with my 500Gb Lacie external HD and a 120Gb seagate external HD that I borrowed. It worked fine up until a few weeks back and now it will not mount and nothing is displayed in disk utility. The external HD has everything of importance in my computing life on it. I can’t believe this is happening. The first thing you’re taught is to backup and then suddednly the backup system is not worth a pinch.
