Subj : USB 2.0, Warp 4, ECS and To : Will Honea From : Peter Knapper Date : Thu Jun 09 2005 08:56 pm Hi Will, Great to see you still hanging around here, I thought we might have lost an OS/2 champion there.........;-) The silly part about my questions is that I actually discovered a lot of my own answers when I sat down and thought about it a bit. PK> 1. How can I tell if my current H/W (probably not) is PK> likely to work as USB 2.0 H/W (assuming an install of eCS PK> 1.2 works), or do I need a motherboard/PCI card based USB PK> 2.0 card? I was hoping some S/W can tell what your USB PK> chipset is capable of... WH> Peter, PCI.EXE should provide the hardware level for you. Yep that finds the chips fine thanks. My own research reveals that USB 1.0 comes in 2 main controller types UHCI and OHCI, while USB 2.0 uses a 3rd type that I think is titled ZHCI. All 3 drivers are incompatible with the "other" chipsets and therefore the chipsets require their specific drivers. WH> It will at WH> least give the manf. and part number of the USB controller and hub - WH> from there it's just a lookup. That said, for your purposes all the WH> USB level means is the transfer rate. Thats exactly what I was trying to determine, what H/W level controllers I had because some devices are reported to only work (well???) on USB 2.0 controllers. I obviously have USB 1 controllers currently, so I was starting to think that I should disable the on board USB chips and install a PCI card with USB 2.0 support and see how that went. But... I wanted to feel that it was all likely to work first........;-) WH> One is a very early USB 1.0 (Via 503+) while the laptop has the WH> latest and greatest USB 2.0 - and I can't see a difference. I have seen a USB Portable HD working on 2 different XP boxes, 1 box was USB 1 the other was USB 2, and the performance difference was VERY obvious. WH> It did take the latest level of USB stuff to get a printer to work WH> under OS/2 - that would be the determining factor. Matter of fact, WH> that and the PCCard stuff was my major reason for getting eCS and WH> access to some of the latest updates. Oddly enough that is my own thinking......;-) I have eCS 1.2 here and was about to move from Warp4 to see if I could get USB working in its full glory. PK> 2. Is there a utilty that I can run on a system that can PK> report all this level of detail? Usb Resource Manager 0.9.7 PK> from OS/2 Netlabs does not appear to display down to this PK> level of detail... WH> Other than PCI.EXE, I would simply go to the mb or the computer makers WH> web site (if you don't have the manuals) and look up the USB spec for WH> your system. That's probably quicker than anything else. Well my machine is a "bittza", bits of this, bits of that.......;-) Its an ASUS CUSL2-C motherboard and I have found that that is definately only USB 1.......;-( WH> If you have a Winxx partition, Wash your mouth out lad, I am stricly non M$ here, 3 x Warp 4 and one (heavily customised) Linux box running FreeSco........;-) The only machine with Winxx on it is my work Laptop, and thats because the company provides it. Needless to say its also the one I have spent the most time trying to "fix"... Now... I don't suppose you have invested in a Digital Camera and a memory stick recently have you? Thats the next part of this project, the wife wants to take some pictures (not of me I can assure you) and send them overseas.
