USB and TPad A21m

Hardware:
ThinkPad A21m
Verbatim 1GB USB Thumbdrive

Software:
eCS 1.25

(partial config.sys)
BASEDEV=USBUHCD.SYS
BASEDEV=USBD.SYS /REQ:USBUHCD$, USBOHCD$, USBEHCD$
BASEDEV=USBMSD.ADD /FLOPPIES:0 /REMOVABLES:1

UHC1 Compliant USB Host Controller IRQ 11

No EHCI controller detected

Note:The Thumbdrive (above) works ok on 3 other computers I have.

After inserting the thumbdrive in the USB slot, the thumbdrive flashes shortly for one burst. This thumbdrive flashes shortly for one burst, slight pause, then flashes shortly for a 2nd burst on my other computers.

The thumbdrive does not show up in the drives folder. Clicking on refresh removable media has no effect.

Anyone have possible solution?

I have a Thinkpad A22m with a similar problem. It has a single USB port in back. I installed the lates USB drivers (from http://www.ecomstation.com ). It has eComStation 1.2 on it. I have checked the bios but there seems to be no mention of an USB port. I did you what you did; click refresh removeable media. It too had no affect on it. I will look for a possible bios upgrade or utility for it from either IBM or Lenovo.

(for A22m but it can be changed for your model).
I hope this helps. I will try it myself.

I had previously tried those sites but didn't find anything related to USB drivers. The solution to the problem may not be drivers but "technique" in the config.sys.

I did not find any mention of an USB port in the bios/cmos settings (there was a mention of a serial port; enabling it stalled the booting of the Thinpad). I had thought perhaps a newer or refreshed bios might show an USB port setting.

Folks,

just for collecting more clues about the situation:

The first thing I would do in that case is to boot up eCS with the stick already attached. Does it show up in the drives folder then?

Next: Regardless of step one - start LVM (or LVMGUI) and see if it complains about a drive... that would at least mean that it was "detected".

Next: You say it works on 3 other computers... is any of them running eCS/Warp? If not: Probably the thumbdrive is formatted with a file system that your eCS doesn't understand - like FAT32 with no FAT32.IFS installed on your machine or NTFS...

Last question:
Does the TP has ONE or TWO or MORE USB slots? Probably there's more than one controller installed but you have only one controller supported by the USB driver... okay, that's most likely NOT the case because eCS install works good in that matter, but one never knows:
So if you have more than one USB slot, try if the thumbdrive works on all/none of them.

HTH
Hope to hear from you.

Greetings
Thomas

When computer is booted up with eCS and stick inserted, it does not show up in the drives folder.

Using LVMGUI it does not complain about a drive.

Other 3 computers are running eCS. 2 are dual boot with w98. 1 is dual boot with XPPro.

TP has ONE USB slot.

The Hardware Manager shows only 1 controller.

in my cases, a resource conflict exists; typically a shared irq which the usb driver can't handle. warpcafe has the right testing idea except that i'd boot using the installation disks like i did on my ecs2.0beta pentiumD test bed. no drivers for other devices will have been loaded.

I checked the Hardware Manager and IRQ 11 is used by:

A. Sound Fusion CS46xx

B. UHCI Controller

Could this be a problem and if so, how to fix same?

Further snooping! I rem'd out the audio lines in config.sys, checked to make sure IRQ 11 was not being used after a re-boot. IRQ 11 shows as being used ONLY by the UHCI controller. Stick is still not recognized.

try turning off audio support in bios. cardbus can be an issue. also is a nic in the system? the hardware manager will not report the irq used for most drivers. the hardware manager does not report if the video adapter is using an irq or not. if adjustable in bios, i set mine to off.

i have this problem also with my tp770x; but, the system is too complicated for me to reload it at this time. thus i don't know exactly why this system doesn't work

i'd still just boot to the install cdrom and see if it works there.

i am out of suggestions.

No NIC in the system. During the boot-up screen, the video is stated to be using IRQ11.

I changed (in bios) the IRQ for the UHC1 Controller to IRQ 5. Stick still a NoShow in the Drives Icon.

Still looking.........

Appreciate everyones input.

Hi everyone,

woohoo - this seems to become a busy thread. Great.
That suspicious resource conflict surely is a good idea to check. AFAIK, most of the "older" sound drivers had severe problems with "sharing" irqs... which means: They didn't.

From my experience I know that one should NOT try to run USB controller "irq-free" which is possible with most BIOSes, because OS/2 and eCS won't be able to use it. But you didn't do that - so this is just for information purpose...

The question now is, how to assign a unique IRQ to the USB controllers and to find out in reverse: Which ones are used?Another hint from zman is indeed inportant: The hardware manager is not perfect! Many drivers are not "hwmanager-aware" so that it cannot display resources used by them.

The best method for that is Veit Kannegiesser's pci...vk (on hobbes; the ... stands for the version number). That is a must-have for all "hardware fiddlers" on OS/2+eCS. Here' sthe link:
http://hobbes.nmsu.edu/cgi-bin/h-search?sh=1&button=Search&key=PCI+agp+sniffer&stype=all&sort=type&dir=/

Oh, yes... one thing: I saw that your thinkpad apparently has not "EHCI" controller... which means in return that it has no USB2.0-capable controller. Hmm... is that thumbdrive a 2.0 device and possibly not downwards compatible?

Greetings
Thomas

Yes, I had an option of running the USB Controller "irq-free" (in bios) but did not try that scenario. Thanks for the "heads up" on that aspect.

I haven't downloaded the pci..vk yet but will do so.

The stick works in 2 other non EHCI computers and 1 with EHCI. That rules out the 2.0 backwards compatibility. Plus, I have a Kodak card reader (cameras) and an Epson 1670 scanner that both work in the 2 non EHCI computers (using eCS). None of them work in the A21m TPad.

Onwards!

Latest "experimentation" and digging for USB functionality.

The stick Works OK if the eCS demo cd is used. I copied the config.x while using the eCS demo. I will attempt to compare my config.sys with the config.x and find the "problem".

Bobber,

ehh... forgive me, but... are you sure the USB socket on the ThinkPad really works? Have you got a device that has proven to work on the socket (even maybe with a "different" operating system - just to check...) ?

With my A22m, it does not see the 64 meg USB drive. The 64 meg USB drive works with my T23. I will try USB resource manager.

With my T23, I tried my USB007 drive. It is 512 meg in size. My T23 does not see it (I tried USB resource manager and it sees no drive). It works with my Win Gateway 200s.
