[help] 2008 Mac Pro (8-core) problems with USB

[rthpjm]

Mac Pro 1,1 has USB 2. Also, he has issues with externally powered devices and has tried USB PCI-e card.

Oops! You're right, I got a bit carried away. I've corrected my post...

So, here's an update: USBs work fine if I boot from an Ubuntu live CD.

 

[pastrychef]

Your completely clean install of macOS has issues???

 

[GermanCorbs]

I did a fresh install which installed 10.11. I created a 10.9 install USB, but it keeps getting stuck on the grey loading screen on boot.

I'm going to try creating an internal install HDD. If that fails, then I'll try a CD since CD's seem to work.
[doublepost=1478704686][/doublepost]It looks like El Capitan was the culprit. I was able to create an internal boot drive for Mavericks, and install it onto my main drive. USBs seem to be working now.

Does anyone know if Yosemite also had USB problems, or is it safe to do that upgrade?

 

[ColdCase]

I have 10.10.5 running on a 3,1 without issues. Seems solid.

 

[OS6-OSX]

I have 10.10.5 running on a 3,1 without issues. Seems solid.

Same here

 

[GermanCorbs]

Cool. Now, I just have to find a way to get the installer app. I don't recall downloading it from the app store. I know I had the beta versions. It doesn't show up in my purchased apps.

 

[pastrychef]

Odd that no other 3,1 owners have reported these USB problems with El Capitan.

Odd that no other 3,1 owners have reported these USB problems with El Capitan.

Unique problems is kind of a common theme with my life. lol

 

[pastrychef]

Well, at least you know for sure that it''s a software issue now. Just need to figure out the cause...

 

[GermanCorbs]

I've noticed that 10.11 has a kext file called IOUSBHostFamily, and that's something that is not in 10.9.
[doublepost=1478792629][/doublepost]

I just searched for the various USB power specifications.
Remember the MacPros of this era will have USB 1.1/2.0 which only delivers 5V up to 1.5A.
It wasn't until mid2012 that he USB spec changed allowing 20V up to 5A

It could still be a power draw issue

Also open the Console app, look at the system log. Connect one of your devices, see if the log gives any indication if/when there is a disconnect event

This is what Console shows when I plug the device in when I try using USB storage devices on 10.11.

Just coincidently -- and I don't want to hijack this thread -- I have a machine that seems to be identical: MP 2008, 3,1, 10GB RAM and now running El Capitan. I have not had any problems with USB ports (including an occasional USB powered hard drive, iPhone, flash drives, and even an SD card reader).

But it seems that since upgrading to 10.11, the machine will drop its Ethernet afp connection to a local server on the network. I don't have any recollection of this happening with 10.10, but it's possible that it did this with Yosemite too.

I've checked this with both Ethernet ports on the MP and it still happens, but fortunately, only every couple of weeks. When it does I'm still able to save data to internal hard drive, reboot, and the problem's gone. Nevertheless it's still annoying.

I haven't used my eternet ports, so unfortunately I can't really give much feedback on your issue.

@GermanCorbs,
The third block of code seems to show that the disk is mounted, but it is out of sync with it's journal. The journal files are automatically deleted and recreated. To get the new journal to sync the system looks like it goes through a device reset. This would explain the symptoms of the device ejecting.

I am not an expert in this field, but perhaps you could rule out a physical problem, have you tried an alternative cable?

I think you said that MacOS X 10.11 is a clean install. To be sure, can you boot into safe mode (reboot, hold down the shift key)....

After that I'm at a loss. Have you searched the web to see if other Porsche Design owners are reporting issues?
[doublepost=1478859528][/doublepost]Are you able to reformat the drive? Does it contain important data?

There are quite a few reports of the drives in the PD enclosures failing....

I figured out the problem (for the most part) last night. Spotlight was the culprit. After adding my drives to the devices for Spotlight to ignore, they work fine. The only issue that I'm encountering is a storage unit randomly becomming unresponsive for about 10 seconds. Files won't open, folders are empty when you open them, file transfers pause. However, it always recovers and continues without corrupting anything.

I have a Mac Pro 3.1.
It runs El Capitan and has 64 gig of ram.
I haven't used it a lot, but I had problems connecting drives to the USB 3 Pci Express card.
They are all drives with external power, they didn't show up.
But I have a powered USB 3.0 docking station and then they work.
I didn't went to the bottom of this ... just hey the Drive doesn't show, plug it in the dock and everything is normal.
What it does do is ejecting all the usb 3 drives when it goes into sleep mode.
I only have it since a couple of days and it came with El Capitan installed fresh from a Mac Pro vendor.

I had similar symptoms with an internal drive. It was the drive that was failing. I replaced it and still managed to get the contents successfully transferred...
