Three new drivers can be found at Hobbes, currently in the incoming
directory:

  http://hobbes.nmsu.edu/pub/incoming/ 

First there are two drivers from  Robert Lalla, Loerrach, Germany
(rlalla@stepnet.de).

usb_com_fix01.zip: USB modem driver, fixed to work with non-3Com
hardware.
 
(from readme)

"This is a modified version of IBM's OS/2 driver 
(Jan-06-99) for USB modems. It should fix some severy 
problems when using modems other than 3Com.

Summary of modifications
------------------------
* fixed bug that caused system trap when plugging hardware 
other than 3Com.
* disabled detection of optional "COMM_FEATURE". My test 
hardware pretends to support this mode, but it doesn't work 
at all.

Known problems
--------------
* poor performance after a few minutes of operation
* PMFax / Faxworks not working
* no hardware emulation for MSDOS / WinOS2 support"


usb_uhci_fix01.zip: USB host controller driver (VIA and Intel
chipsets).

(from readme) 

"This is a modified version of IBM's OS/2 driver 
(Jan-06-99) for UHCI style USB host controllers. It should 
support mainboards equipped with an INTEL, VIA or ETEQ(?) 
chipset, as well as VIA USB addon cards.

Summary of modifications
-----------------------
* added workaround for VIA chipset bug
* added support and autodetection for upto 4 mainboard 
ports. (not tested)
* fixed load message to screen (also fixed by IBM in the 
4/29/99 build)
* various stability enhancements"


Then we have Daniela Engert from Germany, the same person who maybe
made one of best known OS/2 drivers, the DANIS506 driver. Now she
has
given OS/2 users another suprise, support for IOMEGA IDE ZIP 250MB:

daniadsk.zip

(from readme)

"This filter driver supports all of the ATAPI disks that 
IBMATAPI does (LS-120, ZIP-100, JAZZ), and in addition the 
ZIP-250 (including full media swapping).

Current implementation status:
- it suffers from the same bugs as IBMATAPI.FLT
  (except for the trap at APM resume when the base S506 
driver exports forced ATAPI fake devices)
- it is not yet as optimized as DaniS506.ADD"

Future plans from Daniela:
"TO DO
     - optimize
     - merge with the IDE CD filter driver
     - merge with the base S506 driver
     - implement the ASPI interface"
