    PC Card USB adapter

    We have an old ibm Thinkpad 560 that runs Win95 4.0 and we want to use a PC Card USB adapter on it. Best Buy told us this wouldn't work - but some searches on Google seemed to indicate it might work with certain cards.

    Is there any info on how to get a USB adapter card to work on this machine with Win95? Or is there any other way to get a USB post on the machine somehow (maybe using the floppy drive posrt or somethin else)?
    Thanks

    Re: PC Card USB adapter

    I thought that the earliest version of windows to support USB properly was Windows 98 SE2 (or whatever the second edition of W98 was called).

    Re: PC Card USB adapter

    I think the word "properly" is the important one. There was some very flaky support in Windows 95 OSR 2.1 (allegedly available only to OEMs).

    I suppose it depends on how much pain you want to experience. Personally, Windows 98SE with an appropriate driver works with my USB 1.1 flash drives, but I can't then put an USB 2 flash drive in without considerable unhappiness (usually a reformat...). I can use a USB 2 flash drive, but then can't put in a USB1.1 flash drive. A reboot is needed between types. (Your kilometerage may vary)..

    On the other hand, USB support in Windows XP is v. good!

    It's probably not relevant to this post, but my personal experience doesn't agree with "very flaky". My previous home PC was a Dell with Windows 95 OSR 2.1, and the USB ports worked fine - plug and play without any problems.

    Re: PC Card USB adapter

    I suspect this is another Your Mileage May Vary event.

    At the time when the OSR stuff came out I remember howls of protest about lots of USB things that did not work properly. (Remember the phrase "plug and pray"?!)

    I vaguely remember we tried some USB stuff for "the laptop users" (Compaqs, in those days) who wanted to use the new gadgets on Windows 95, but had so much trouble we said that we couldn't support them until they (and the drivers) became more reliable...

    But it was good that your machine worked well!

    Re: PC Card USB adapter

    Windows 95A doesn't "do" USB. Windows 95B and 95C will let you use USB, but, as John points out later, they need to be OEM versions of 95, unless my memory is failing. It's been a long time since I've dealt with 95B, and my copy is OEM, so I can't be sure. But, I do know that the USB ports always worked fine on my antique Pentium 2 running 95B. Maybe I just got lucky...

    Re: PC Card USB adapter

    I was able to install Win 98 on the Thinkpad. BUT this made my problem worse. I no longer can control the instrument that is the sole reason for using this laptop. The control software works in DOS and thru the serial port. I think I recall soemthing about how Windows stopped being an interface "on top" of DOS at some point and merely began to emulate DOS. Could that be the problem? Does DOS in Win 98 act differently re the serial port compared to Win 95? I can't figure out why we can't access our instrument anymore....

    </center>Because you changed your basic configuration when you installed Windows 98.

    I'm curious as to why you did that if that machine was the only one that could control this certain "instrument". With the discussion trending towards USB operating with Windows 98 & 95 only on OEM machines and no information suggesting that you installing a new OS on this machine would solve your problem, I can't figure out why you did this. I don't suppose you have an image backup of the old system ?? Short of reinstalling from your original recovery disks for the Thinkpad I don't know if you will be able to recover this functionality. Did you reinstall the underlying software for this "instrument" ??

    Re: PC Card USB adapter

    We wanted to be able to simply transfer data from this machine to others using a USB based flash device -- that's why. I had no idea that Win 98 would screw up the serial port operation.

    Your reply is not clear as to whether the DOS 'sub-system' functions the same way or not under Win 95 or 98. That is the question I have if anyone can answer it. Thanks.

    Re: PC Card USB adapter

    You can read about DOS for 95 & 98 here. They are for all intents and purposes the same animal. I doubt that it was the actual installation of 98 that did in the serial port. More likely it has something to do with drivers being different. Check into updating the drivers.

    It would help us to help you if you would tell us exactly what it is you are trying to do. I understand that you are trying to get the system to support USB to use a flash drive for data transfer but what is this "instrument" that you are no longer able to operate ??? Is it a tuba and you are embarassed to tell us that you are trying to play the tuba with your laptop ??? <img src=/S/laugh.gif border=0 alt=laugh width=15 height=15> Or are you using something to transfer data via the serial port and now are up the proverbial creek ???

    Re: PC Card USB adapter

    It is the latter - a Campbell Scientific CR-10 datalogger that relies on the laptop for programming, uploads and downloads of data - once set it is autonomous and field operable. It is a slow device but highly accurate - we use it to acquire temperature and other data from micro-meterological sensors. It uses a 9 pin serial jack for comm. It all worked just fine (for many years) before the 'upgrade' to Win 98.

    I looked at the web site. Liek others I've seen, I can't tell from the description what the author knows and doesn't know re serial port operations under Win 95 or 98.

    Thanks for any help.

    Re: PC Card USB adapter

    I've attached a screenshot of a section of the manual for the CR-10 Datalogger that seems to indicate that there is/was and arrangement between Campbell Scientific and IBM to make their devices work together without any software interface. When you "upgraded" to Windows 98 you most likely wiped out the OEM comfiguration for that interface. Perhaps if you read the manual you can find a way to get this capability back or if you have the original disks for the Thinkpad you can do a recovery installation with the CD's provided by IBM. It will wipe all the data off the computer, so backup anything you value if you choose this route, or it will be lost. HTH <img src=/S/shrug.gif border=0 alt=shrug width=39 height=15>

    Re: PC Card USB adapter

    Thanks - but there is no particular connection between the comapny IBM and CSI -- the manual is referring to what used to be known as the IBM PC -- i.e. the geneirc standard for IBM and the alter clones of it as opposed to an Apple II or Mac..

    What you describe might nonetheless work -- assuming no one has tossed out the original Win 95 install disks.

    But IF there is a a way to get the serial port to work "correctly" under Win 98 I'd prefer that... any ideas on that?.

    Re: PC Card USB adapter

    Have you tried another serial device (if you even have one) to verify that it's the serial port and not the device or it's interface ???

    The first page of the manual talks about the "use of the PC208 Data logger Support Software" and I'm wondering if you have that installed after the upgrade. I'd guess that the software came with the CR10 and was installed on the laptop by you or one of your associates. It appears that this will be necessary to get from the Telecommunications State to the Remote Keyboard State that is required for communication with the laptop or any other computer. Another screenshot from the manual gives the basic computer requirements. One of which is a computer programed to function as a terminal. Is the laptop still programmed as a terminal ???

    Just in case I'm on the wrong path here I'll backtrack and check into the serial port issue and if I find anything usefull I'll post it.
