Re: TPT2 has USB port power issue

2013-01-07, 18:54 PM

03rst can you clarify, did those devices fail only under the WinPro that came factory installed, or did they fail with the Win Enterprise installation?  You seemed to hint that non powered USB devices were working under Windows Enterprise but I'm not sure if that's what you are saying.  Can you detail the differences in what hardware works and doesn't work in each particular windows install?

 

I have a WinPro 8 install DVD I was going to install over the Lenovo installation but my Asus DVD doesn't work, even with a Y cable.

 

EDIT: Read your initial reply a bit more carefully where you say:

 

"I have also used a USB hub to connect a mouse, keyboard, DVD and hard drive mentioned above, a USB key and a USB network dongle. All of them are detected under Windows 8 Enterprise and work fine."

 

Which is great news because it has to be software related if that hardware all worked under WinEnt but on the same tablet..  I may take a drive up to Microcenter and pick up a powered hub and see if I can get a different version of Windows installed to see if that makes a difference.

spindoc. The results you see are from the factory W8 Pro install and my W8 Enterprise install. The only device I was able to boot to in any case was the Lenovo (unpowered) DVD drive. The powered USB hub had no affect on the other devices as BOOT devices.

 

Once the tablet was booted into Windows (both Pro and Ent) it could read the USB key and DVD drive when each drive was connected directly to the tablet USB port. The portable USB drive failed under both. Once I connected the powered USB hub to the tablet, all 3 devices could be read from within Windows. I hope this answers your questions.

I think the key thing here is the Lenovo DVD drive. I stock this particular drive for our X230 and X1 Carbon users. This drive only has a mini USB connector and was designed to get all of its power from a standard USB 2.0 port. The actual drive in this part is a laptop DVD. I don't have any other external DVD drives on hand to see if they will work as well.

Thanks 03rst,

 

But there's no key thing here. The only thing that is happening is robbery.

Thanks for the clarification 03rst, so only the Lenovo DVD drive works, but that's a usb powered drive only.  Isn't that kind of odd, this means that at least one drive works unpowered so it's not that the usb port isn't putting out enough power, it seems to be that either a) the other usb drives are incompatible, whether they need more power or something else who knows, or b) that Lenovo has some kind of a check on what hardware it allows to be used over the USB port.

 

It's probably the first one.  I know with this Asus DVD drive that I have it's hit or miss which laptops will power it, and which ones won't and need the power cable, although I'm baffled as to why it won't work with the TPT2 even though it's connected to an AC adapter.

 

In any case it would be nice to have an official word from Lenovo before my return period is up.  I'm seriously considering switching out to the Dell Latitude 10 but I really like the Lenovo otherwise.

Re: TPT2 has USB port power issue

Yea I agree with you there. Like most early adopters we pay the price or lay the groundwork for what follows. We purchased these as a travel companion and not a replacement for our X series laptops. I did expect some limitations since it is an Atom based system. Remember, this particular device is competing against Windows RT and other SOC based hardware platforms. This is the bare bones minimum to run a full blown version of Windows 8. Everyone has their own requirements. I never envisioned using USB hard drives with this device.

 

The TPT2 is a $750 system which is over inflated for what it can do. Compared to the Samsung Series 7 slates we have, this thing is a toy. It should be since the Samsung is double the price. Its a laptop without the keyboard and performs as such. I didn't have the same expectations for the TPT2

That's not correct. You were right if none of sub $800 Clover Trail tablet could not read/detect unpowered devices.

Asus, Samsung, Acer and Dell do this like a charm. They are PC after all.

Yes that's the disappointing part, EVERY single other cloverfield tablet currently out can read external drives over USB, that's why it's so baffling and honestly a bit unbelievable that Lenovo purposefully didn't design the TPT2 this way.  Now knowing that it does power *some* usb drives there is at least some hope that it's not a hardware issue, but we're all in the dark until Lenovo says something.

 

I've got to say though that the Cloverfield CPU has impressed me quite a bit, I wouldn't call these "toys", that label belongs fully to the ipad which truly is a toy.  I have the feeling I'm on a full PC, Office, Photoshop, etc just amazing, I think many of us will be hard pressed to truly push the device and really the need for an ivy bridge processor is overstated by many, although we are definitely early adopters and by this time next year, if not sooner, we will have better cpu's.  Cloverfield is still a netbook processor with some optimizations, but it's certainly not a new design or anything.

 

Still, my main goal was a "real" PC in the form/battery life/weight of an ipad and I think it's accomplished it's goal quite nicely.  This USB issue is nasty though, and honestly I look back and think I liked the Acer W510 I used for a couple of weeks better overall, except it has no digitizer.

The worst thing is Lenovo's staff in this forum have not responded to this topic yet.

I blamed the first TPT's failure for the OS, but now it seems I was wrong.
