After upgrading from Panther to Tiger, my US-122 stopped functioning. The USB light does not go on, and my computer does not find the US-122. I called up Tascam support; after being on hold for about an hour, they had me delete all US122 files, restart my computer, and re-install the 323 software. No luck. Tascam support told me that the problem must be with my computer running under Tiger, since (a) They have had no problems running under Tiger, and (b) the unit was working on my son's iBook running under Panther.

To verify that the problem was my computer, I upgraded my son's iBook to Tiger. However, once I installed Tiger on my son's laptop, the unit stopped functioning, and now the USB light does not go on when attached to my son's machine. So just to triple check, I installed the 323 software on my daughter's iBook, which is still running Panther. The USB light went on immediately!

Tascam support insists that there are no problems running under Tiger, yet I have reproduced the problem on two computers. All suggestions are welcome, but yes, I've tried switching cables, USB ports, etc, etc. If it matters, my computer is a four year old G4 (Silver CD Doors) running 10.4.1 and my son's laptop is a 4 year old G3 iBook Dual USB running vanilla 10.4.

Am I the only person experiencing this problem? I'm hoping to keep this unit, since it has been performing fine for a year and a half. But if it doesn't run under Tiger, then I shall have to replace it (and it won't be a Tascam product). Thanks in advance for any help you can provide.

If it has not been done already repair permissions using Apple drive utility, then make an optimize prebinding using OnyX (to stay simple).

What are the other peripherals on USB plugged in?

I won't be around to follow this, but that's the things I think of… Note the US-122 seems to be temperamental, have a look on this search, maybe there's something for you.

Just thought that I would throw in my 2 cents on this subject because it seems to be popping up alot on the forums now. If your current setup worked with Panther, it probably would have been best to stick with it. It really takes a while for the hardware manufacturers to catch up with the lastest OS revision & make new drivers to address the bugs. Why fix something that really isn't broke? Never mind Mac's sales pitch for their newest offering. I have heard from people with much more knowledge than me on the subject that Panther was about the most stable OS out there & later revisions were "dogs with fleas"- this is probably an exaggeration but, again it takes hardware manufacturers 3 to 6 months to revise their hardware accordingly.

Just to keep anyone who is following this up to date:

1) I tried repairing permissions, it didn't make a difference.
2) The US-122 is the only peripheral plugged in (apart from keyboard & mouse)
3) Doing an optimize prebind seems a little risky to me. The OnyX software was in beta for 10.4, and I'm leary of tinkering with OS internals. But I'm going to do some more research on this.

In answer to MortalEngines, with 20/20 hindsight it was a mistake to upgrade; however in the past I've run into trouble for not updating soon enough and I ended up with orphan data which I could not upgrade at all. perhaps I'm over-reacting to that incident.

That said, if Tascam had clearly posted on their site that their driver didn't work with Tiger, then it would be my fault and I could accept that. However, Tascam has stated on their web site and to me personally that the driver works fine. So one of two things is happening. either (a) Tascam is lying or mistaken OR (b) I'm doing something wrong. I'm hoping for the later. So if anyone out there has gotten a US-122 running under Tiger, would you let us know? Thanks!

For what it's worth, I installed the latest US-122 drivers on my 15" PB last night, running OS 10.4.1, and the U2-122 unit lit up and seemed to work fine.

I hear you & sympathize & when Mac just put Tiger out they did imply that their latest revision was going to work with TONS of different hardware & they do a great job of trying to push it off as essential. Between them and Tascam I am sure that you are dealing with corporate Jerks & the bozos in tech support/development tend to be unhelpful, if a bit arrogant to boot.

Good Luck!

I don't have the Tascam unit but I looked at Tascam's site for a little to see if there were any leads. I know this sounds stupid but did you try a different USB cable? Also I don't know what kind of computer you have but in the manual there is talk of firmware updates you may need depending on your computer.

Hey there eheilner, I have the Tascam US-122 and Tiger and had the same problem you are describing. However after a reinstall of the plug-in from Tascam it all started working again. I would recommend prebinding your system as well and if Onyx in still in beta you can try Cocktail an application that I use and have tested on tiger.

The last resort is a re-install, but fingers crossed right!

I would just like to say that i haver had the same problem of losing my us-122 activity when upgrading to tiger. I tried updating prebindings and re-installing the software but no good. tascam have not replied to my e-mails. The phantom power switch does light up when it's flicked across bu the usb light is out. i don't know what to do now.
Cocktail didn't work for me either.

peteDOGG -

This is good & bad news. Bad in that our units aren't working, but good in the sense that we're not alone, so we know it's not our fault. It would be a big help if you tell us the year & model of your machine. Since it works for some people but not others, and since my machines are about four years old, my working hypothesis is that there is an incompatability in the driver software for older machines.
