T61 "USB Device not recognized"

2008-02-14, 4:39 AM
This is staggering! I'm on the phone with Lenovo Canada and am being informed that the USB port on the right side is underpowered as a result of poor motherboard design! Shocked The two on the left side get full power, but the one on the right does not. They have informed the mobo manufacturer who is trying to come up with a workaround, but until then printers, wireless mice, etc., may experience the "USB Device not recognized" error warning on the port. My issue is with a Logitech VX Revolution mouse. I really want to get the USB wireless transmitter up out of the way as it's plugged in all the time, but it won't run up there . . . I've got a flawed machine, and Lenovo knows it. What do I do?!

[edit]: 43 minutes later (I need a speaker-phone!) the problem has been "escalated to level 2 techs" to see if they can reproduce the problem (case number 00060S9).

Unless they replace the motherboard, there is not much else you can do, except use the other 2 USB ports (up to 147 items per port, should be enough for everybody!).

But the whole point is that there are 3 USB ports on the machine and only 2 of them operate at USB 2.0 specs wrt power. And the two on the left are much closer to my hand movements than the one on the right, so if something is going to be plugged in fairly often (as a wireless mouse is) the logical place to plug it in is in the port on the right which is further out of the way. I think I'm going to campaign for a new motherboard. Do any other T6x users experience this or is it unique to my machine?

Lengo,
 
I think there is a thread on this over on ThinkPads as well.
 
I believe your account of what has transpired, but would ask that we check this out carefully before alarming a lot of folks on the board, starting petitions, campaigns and so forth.
 
Thanks
 
Mark

Thanks for the input, Mark. In reply, however, anyone who hasn't experienced the same behaviour needn't be "alarmed" (though I will admit I was when the Lenovo representative informed me of "flawed motherboard design" [his words, not mine]). Second, I don't recall starting a "petition". . . And my only "campaign" is to find other users who have experienced the same behaviour (so far I've found one). I can appreciate your desire to keep the "feathers from flying"--I'm not trying to do that--but one way I can "check this out carefully" is with the help of others with similar experience. I thought this might be a place to do that . . . I'd also appreciate any assistance you could provide in 'checking it out'. Thanks.

Lengo,
 
I apologize.
 
I didn't intend my comments to sound as a rebuke, I'm just rather serious sounding most times.   I'll work on putting more :smileyhappy: along the way so people know I'm not as heavy as I sometimes sound. :smileywink:
 
Truthfully, I'm glad you shared your stories here and on TPF because we need to understand the kinds of experiences our customers are having.   You absolutely , are doing the right thing, and it is appreciated !
 
 My comments were mostly in response to the comments on TPF from others suggest system board replacement, the concept of "known" flaws, etc.  
 
Having checked with L2 and product engineering, all 3 ports are believed to have the same spec, USB 2.0, and what you, and the other member on TPF have reported is not a "known issue" at this time.
 
Could you send me a PM with your model and serial number, and a bit more about the mouse, including perhaps the driver information (version) etc.   This would allow us to look into the matter more completely.
 
Thanks!

Not only have I experienced this on my T61, but also on my T42 as well.
 
Thought it was just the way it was...

Which devices prompted the error? And on which ports? It'd be helpful to know.

On my T61, it is on the right side.
 
I cannot connect any external hard drives that require power, nor can I connect an iPod, mouse, or keyboard. They all work perfectly on the left side.
 
My printer does work on the right side.
 
My T42 is in storage, but it had the same problem. I just forget which side.
 
I do not get any error messages. They just do not work, and the computer does not recognize them at all.
 
I hope this helps!

Thanks, TrishaK. It's nice to hear it's not just me w/ USB problems on the right side! I mean, it's no good that there's a problem, but if it's more than me maybe they'll take it more seriously. There are a few others at forum.thinkpads.com w/ the same issue. I'm going to try bring this to Mark's attention and see what happens.
