Subject:  [VOICENWS] Drivers: New USB host controller drivers: usbhcd186.zip

++ From the VOICE OS/2-eCS News Service   http://www.os2voice.org ++ 

From: lars.erdmannDESPAM at DESPAMarcor.de

I have updated the USB host controller drivers
USBUHCD.SYS, USBOHCD.SYS, USBEHCD.SYS, USBD.SYS
I have now placed these on hobbes.
http://hobbes.nmsu.edu/download/pub/incoming/usbhcd186.zip

They will eventually make it into directory:
/pub/os2/system/drivers/misc  

1) USBOHCD: fixed http://svn.netlabs.org/usb/ticket/22#. Everyone that
uses USBOHCD.SYS and cannot get any devices attached at all should use this
fixed version of USBOHCD  

2) USBEHCD,USBUHCD,USBOHCD: partly fixed http://svn.netlabs.org/usb/ticket/23# (sudden reboot on shutdown), the  

remaining problems might be fixed with 3)  

3) USBD.SYS: major update, changed to dynamic memory allocation for DeviceInfo structures, this fixes these errors:
http://bugs.ecomstation.nl/view.php?id=1400
http://bugs.ecomstation.nl/view.php?id=3010
What it means in practice is that USBD.SYS will no longer trap when you attach devices that return a whole lot of configuration info (some webcams from Logitech being a prominent example). The device might still not be supported but the trap is gone and you can look at device info from USB Dock / USB device manager.  

 

A short note (also in readme.txt): DO NOT use XCenter USB widget !
It's badly broken and can do all kinds of bad things to your system, including a trap8 ! File readme.txt contains some REXX code that will recreate the USB memory stick daemon (that came with eComStation 1.2 and that works perfectly well).
