USB hubs and devices can cause installation issues Install
This occurred on a G4 AGP trying to reload software on a two drive (master/slave) system. Booting from Jaguar disk, when it got to the point to choose a destination drive.. none were visible to choose. Also noticed OS 9 would not shutdown properly, hangs when choosing "shutdown" menu. This also prevents firmware updates from running properly.

Solution: It was the extra USB hub and devices (printers, scanner, etc.) Unplugged the extras, leaving only the keyboard in one usb port and the mouse plugged to the keyboard. Drives now visible and OS 9 shuts down properly. I don't have a clue why this happens but I have tried it on two different G4s and it is a consistent bug.

[robg adds: Without more detail on the devices and the hub in use, it's hard to say for sure, but I'd bet this was caused by the hub more than the devices. There were many reports of similar problems with certain USB hubs in 10.0 and 10.1, but this is the first I've heard with Jaguar. If you're having a tough to diagnose installation problem, try removing all the non-stock parts from the machine in question and see if the problem goes away...]

USB hubs and devices can cause installation issues

Re: Hubs that have cause problems in the past

I'm just about to purchase a USB hub and a FireWire hub (or perhaps a combo hub). A listing of hubs to stay away from and hubs that work great would be most appreciated!

Belkin USB Hubs
Authored by: bedouin on Apr 03, '03 03:51:13PM

Anyone else have a Belkin 4-port USB hub? I've been using it for months now, and although it works with no problems, all of its indicator lights for each port stay lit, even if there's no device attached to the port. Not really an issue, but still kind of weird. I'm pretty sure it does the same thing in OS 9 as well.

Belkin USB Hubs
Authored by: WillyT on Apr 03, '03 10:55:19PM

Belkin 4-port powered running a Fastlane and a TI floppy.
Yes all lights lit.

Had some install probs a long time ago. So of course disconnected everything. Once booted plugged it all in and left it plugged in. Rebooted for next install and all ok.

Oh and I have an I/OGear 4(5) port USB pci 2.0 card which I did not remove.

Belkin USB Hubs (not really a 10.2 issue)
Authored by: knowmad on Apr 08, '03 11:53:29PM

I have had two computers recently have problems with belkin hubs. Both times the specific problem was that the mouse would stop working. Keyboard worked fine, mouse simply did not responed (though the optical light would dim and brighten with use and disuse as per normal, the mouse icon did not move no matter what) the fix turned out to be removing the belkin 4 port hub and rebooting. I spent a whole workday testing it because I could not believe that could be the problem, but it turned out to be true.
just to be thourough, the mouse and keyboard (mouse plugged into keyboard) were plugged directly into the mac on one machine and into the hub ont he other. I tried updated software for the other preiphrals, I tried several diffarent chain orders for the USB chain, including mouse directly into machine, mouser and keyboard into hub together and seprate, and for the sheer fun of it, two hubs with he devices spread among them. The problem returned within twenty minutes in all instrances where a hub was plugged in.
The OS, BTW was 10.2.3, but the problem only showed up in classic or when loaded in 9.2.2 so i think its a classic/9 issue not really a 10.2 issue.

USB hubs and devices can cause installation issues

I've heard that the Pertech is a hot ticket. High powered too.

Check it out.

I think I'm gonna grab one and see if it helps my sleep problems in my MDD

cheers

My Belkin 7 port (powered) has been pretty good. It's actually been more reliable than the Entrega 7 port (powered) that it replaced.

cheers

USB hubs and devices can cause installation issues
Authored by: ddldreaming on Apr 03, '03 11:23:51PM
I've had a Belkin BusSwitch 7-port USB for several years and have been generally happy with it, but sometimes I have problems that can only be solved by shutting down the Mac and unplugging the hub from its AC power source for a moment. The most common symptom which leads me to do this is my EyeTV ceasing to work through it. Luckily this is quite rare: once every six months or so.

I also have a MacAlly iMediaKey keyboard which prevents deep sleep on my G4/AGP (I didn't discover this for years, until after I removed a SCSI card that also prevented deep sleep). I ended up buying an Apple Pro Keyboard and now she sleeps happily.

USB hubs and devices can cause installation issues
Authored by: dennishenley on Apr 04, '03 08:30:27AM

I've also had problems with a USB device. I could not boot into a
previously working flatpanel iMac. All I got was a grey screen of death.
I could boot into OS X, but not into OS 9. Finally, after wasting too
much time with original CDs and repair tools, I unplugged all my
devices (firewire and USB) and was able to boot into either OS. Then by
trial and elimination, I discovered that it the USB side of the equation
was preventing booting into OS 9. More trial and elimination and I
found out that a cable was bad. Once I replaced that USB cable, I could
use the hub and all the devices again and boot into either OS.

USB hubs and devices can cause installation issues
Authored by: magir on Apr 08, '03 03:46:22AM

I've got an IIyama-TFT-Display with an internal passive usb hub (not powered) when I plug in more than two devices it starts acting strangely. I use a USB-Switchbox zu switch between two machines and this works flawlessly with two devices (keyboard and mouse) but when I add a usb2serial-adapter or a printer they keyboard and or mouse sometimes stop working and even kernel crashes occur. Under OS9 I got warnings when a device uses to much power but as it seems this isn't implemented in OSX (yet). I guess this is related to that issue.

Macally USB-UH Hub lost me $200
Authored by: ryuukosan on Feb 01, '04 10:59:45PM

Without any exaggeration or frustration, here are the facts:


I bought a Macally USB-UH 2.0 firewire hub and the firewire ports didn't work. I returned it through snail mail from the company and got a new one (that came in a box with no packaging). When I hooked it up to my Powerbook G4 (with 3 USB devices in the new hub), neither the firewire ports nor the USB ports on the hub worked. I unhooked it and replugged the three other usb devices into my other hub (belkin 4port which works beautifully) and I had found that all the devices I hooked into the second non-working hub didn't work in any port. Now my keyboard, mouse, and wacom tablet don't respond to any port. Can anyone tell me what happened?

My answers so far are:

The hub shot a circuit in all three devices (how does this happen?)
The hub reversed the polarity in the devices' cables (how?)
The hub blew fuses in all three devices (again, how?)


Any answer would help me solve this mystery (even though $200 worth of peripherals seems forever gone due to a macally hub).
