content: As in the topic, the problem of a large number of adapters :NI GPIB-USB-HSFrom software version 17.6 (NI 488.2) all Chinese adapters (mainly bought on ebay)are detected as not genuine.So far the solution is to use software version 17.0 (which is also not available on the NI website).But is this the only solution?According to me, there should be at least 2 more:1 - finding a module (entry) in the software which, after detecting an incorrect number, throws this error.2 - (or even better) find the entry in the adapter's flash memory where the serial number is and change itHas anyone tried to deal with the topic?So far, I have not been able to find such an entry neither in the software nor in the memory of the adapter, most likely this value is encrypted in some way.Although we may be able to achieve something together.

content: At first glance, I suspect to serial number stored in separated I2C EEPROM. NI in the recent version of his software put to the backlist the device whom EEPROM contents has been cloned.The solution is to reprogram the serial number in the mentioned memory. If you have access to at least one genuine NI adapter, compare its content with the genuine one.Reading out EEPROM without desoldering is elaborated on car radio forums.Georg

content: Fake Agilent GPIB-USB? No they are all original and new. Now for sale due to that they bought too many in Hongkong at $600 each, now selling them with $500 loss.https://www.ebay.com/sch/i.html?_from=R40&_nkw=82357B&_sacat=0&_sop=15&rt=nc&LH_ItemCondition=3

content: Quote from: Kosmic on September 05, 2021, 11:07:14 pmWow. That's a good fake. Do you think they ran these on a ghost shift or did someone not only try to copy the schematic, but the layout as well?

content: A fake for a start#1 Doesn't have copper paint as a shield, and the copper is supposed to be seen from the screw holes in the plastic shell#2 The serial number has been blacklisted#3 working eeproms dump repositories somewhere.....It's getting complicated to follow many threads as i needed an usb gpib adapter and was going with the arduino gpib route ...
