serial port - Arduino programming using USB download fails on Windows 2000 -

-

i have number of windows 2000 systems trying use program new arduino uno , mega devices. these boards come usb connection, upgrade prior ftdi. i'm not able download arduino code board windows 2000 system

the supplied drivers *.inf files modify standard usb driver comes windows (in case windows 2000).

i go through process of setting port, setting device , doing download. download fails, , apparent error pc can not communicate board. i've checked port, adjusted baud rates, etc. i've moved port number high port number (ie com12) lower port (com2) without success. see activity on rec/xmt lights on arduino board, type of data being sent , received.

i'm looking for:

someone has been able download files windows 2000 arduino

or

a way shim inside usb driver able watch traffic going , down board can continue debug this.

or

some general tips things @ in .inf file need set/not set make work on windows 2000.

i know boards work i've used them on different set of windows xp systems. know extent install , of have works.

full dumps can found on arduino forum, http://www.arduino.cc/cgi-bin/yabb2/yabb.pl?num=1291090110/.

this information produced avrdude program while it's trying download code.

this long shot, jsut recentlz had problems uploading too. fist of all, how long usb cabele uploading from? mine in 1 case long , th arduino woul lose sync. secondly, , might silly oversight (like did) have things wired in digital pin 0 , 1? these used communication, , if there else plugged in them upload fail.

as said, long shot 2 errors had.

i trying use snmp4j snmp bulkget. when ever use snmp4j make call returned responseevent error says "general variable binding error" , data returned equal null. to debug: print out, console, exact oid , version number using in snmp4j. use printed out data snmpwalk on command line. valid results. know sending snmp4j correct pdu correct oid, version number, max repititions, etc. i have used snmp4j , code wrote succesffuly monitor other devices years. don't know different time. leaving me stumped. why "general variable binding error?" causes error? ideas debug? can reproduced? if so, first action should using wireshark or microsoft network monitor capture network packets. my guess agent gives generr response, not surprising, http://www.ietf.org/rfc/rfc1157.txt
