| Hi all, I have MoBO with USB 1.1 HW (Abit KG7), latest USB drivers (USBMSD v10.135, etc), but using USB is only partial success. My problems are: 1.Attaching 64MB mem key is properly served by system, but read speed is about 55-60 kB/s. I can write with 650-700kB/s, but reading is so slow. Is this normal in OS/2 & USB area ? 2. Attaching mem sticks with size above 64MB is impossible. I already tried 3 different 128M & 1 type of 256M keys - no joy. Have You any ideas what is wrong ? 3. I have 7in1 Genesys reader (ID:0x0927). USBRES recognize my card reader, but after inserting 256MB SD card nothing happens. Order of reader attaching/card inserting doesn't matter - it simply doesn't work. I made some tests with CW USBMSD v1.2b. Using it with IBMRSCSI.FLT & /FORCE_TO_REMOVABLE gives possibility to use my SD card but only one card at system up (for reading another card i need reboot system - there is no effect by refresh after card change - with new card system shows content of previous card). Have somebody any ideas what is wrong here ? |

| IBMRSCSI.FLT & /FORCE_TO_REMOVABLE ... ... seems nothing having to do with USB !!! It seems that your USB is either not complete done (Basic plus respective USB unit related) RTFM may help !? |

| Based on the board specs it can also be due to the fact that it's a non intel based chipset board. I have had problem with SIS-based boards earlier (in your case the board has VIA-chipset). In one case when using SIS-based board I had problem to get USB to work I just shifted over the hard drives to a board that used Intel based chipset and the system worked as supposed. Having said that I know that it didn't sound that great. But are there other parts that works as it should? For example connecting an USB scanner and using Tame/2 for scanning? USB 3.5" diskette station? |

| Please attach your config.sys to a reply; it would be easier to check if it's correct. |

| Well, OK, here is my CONFIG.SYS. DEVICE=C:\OS2\LOG.SYS BASEDEV=IBMRSCSI.FLT SET EPMPATH=C:\OS2\APPS; DEVICE=C:\OS2\BOOT\APM.SYS DEVICE=C:\OS2\MDOS\VMOUSE.SYS BASEDEV=USBUHCD.SYS REM BASEDEV=CWUSBUHC.SYS /V SET DISPLAYTYPE=VGA REM BASEDEV=DANIATAP.FLT CLOCKSCALE=4 REM *** WatchCat 2.1 device driver - REQUIRED DEVICE=C:\Util\wc\xf86sup.sys BASEDEV=cadh.sys |

Ups! This got hard to read; please modify the posting by removing the entire config.sys and instead attache the config.sys as a file attachment. This is done by marking the Preview your post and/or attach a file? just above the Post button. |

| Hi Warpcafe, > the SCSI systems require a lot of additional work in order to make them "recognize" USB MSD devices at least. What do you mean by this? I have a mixed scsi-ide system, and I'm having *BIG* problems using an USB memory key (You can find a thread in this same area, regarding problems with an Hamlet eXagerate 128Mb pen drive). I can not even have the system *recognize* that the key has been inserted (even with the new 10.135 MSD drivers). Please, if you have some more suggestions I'd like to hear from you. I didn't even know that having a SCSI system might change the way USB MSD devices are recognized. Thankyou! Cris |

| What about the system IRQs are there any overlaps? If the USB controller share the irq with some other device, try to use another IRQ if possible. I noticed on an laptop that shared IRQ betwen the cardbus and USB-controller made the system to not pick up the usb key memory. |

| Regarding the following line: BASEDEV=USBMSD.ADD /FLOPPIES:0 /REMOVABLES:4 /FIXED_DISKS:0 /FORCE_TO_REMOVABLE Have you tried just to run with: BASEDEV=USBMSD.ADD I played around with the parameters as well, but adding too many parameters just made my system to ignore the USB memory. Do you actually have 4 removable units? Try to strip of the paramters and see how it works out. |

Folks, this reminds of another fact - maybe this could help to some degree: Greetings |

Cris, I'll do my best, but I can't promise you the perfect solution to this question. Certainly, I might not know all the facts about how OS/2 operates with MSD's in general and how this is related to SCSI... but I I always wanted to find someone who explains me how the layers of drivers are ordered and how they operate in conjunction, but... maybe I'll ask Daniela Engert at Warpstock Europe. Storage device driver programmers should at least be able to explain what depends on what... so be warned, that I might have a wrong picture of it! With USB, you first have the lowest "layer" of drivers: Those who operate UHCI, OHCI or EHCI controllers (like USBUHCD.SYS). The *core* question now is, whether USBMSD.ADD does everything needed to show up a USB MSD device as a drive. I'm not sure. I think that there is some more dependency with the OS2DASD.DMD driver. But again, I'm not sure. In addition, I don't know if the IBMRSCSI.FLT does provide a "parallel yet different" way of talking to such devices or if it needs to run on top of the other stuff. Maybe some day, I'll know the truth about USB on OS/2... if I will, I'll certainly drop by here to let you know. But for now: sorry, Greetings |
