I bought VP598 few days ago on AliExpress. It worked well for one day i have tried to read some eproms... after 2 days i wanted to write some eproms but in device manager i only have "Unknown device" when i plug it in.I have tried to get help from distributor but i think they cant help me.I have tried it on other machine it didnt work - same problem "Unknown device". Then i tried another USB cable. I dont have idea what to do. Any help would be greatly appriciated.
I have a VP996 programmer and I can"t read at89c51cc02ca prcesorwhy ?
Can anyone confirm that this is not just my VP390, but a general design or pattern problem, and is there any way of testing for Hi-Z outputs or two-supply (level-shifter) devices?
It is possible to add support for this ?
With new VP898 and device K9GAG08U0E I got Man.code: 00 Dev.Code: FF, if I press retry I got correct codes: Man.Code:EC Dev.Code:D5 , bud trying to read or program fails. Tested on Win7 32b and win7 64b
Someone tested VP898 + K9GAG08U0E? Someone can help?

How can I do that?
I am using ATMEL AT28C256 and Catalyst CAT28C256 chip.
when I remove the top pcb, it will initialize ok, so I think the problem is on the top pcb.
Do you know wich component to check?I"m not interested in sending it in for repair, as it is almost ten years old.
Can you help me?
So I get 2 times the same info of the first page instead of page 1 and then page 2.
The adressing of the second page is not correct.
The programmer, or the software contains a mistake.What can I do?

VP990 support this chip?ISSI IS62WV1288BLL TSOP32
I have VP990, and i use these 2 adapters:
WL-EBGA64-E145 for my BGA chipsWL-TSOP56-F640 for my TSOP chips.
I am buying the new VP998.
Can i use these 2 adapters on the VP998 ?
Do not find Adapter! Set Adapter: Run <Read> without chip on the adapter!
VP-480 on it with two adapters works perfectly.I have two WL-TSOP56-640 adapters.
Which is better, VP998 or GP600 ?Which one is newer ? and which one will receive updates longer.I ask because i have VP990 which i bought for 500 Euros and now no more support and no more software updates !!
