Does someone has dump for 24lc128 eeprom v1.3r2? My UUSP upa was working fine, and today it say’s usb device not recognized, I try with dump from v1.2 but working only one time after disconnect and connect again same usb device not recognized.
solution from obdexpress.co.uk engineer：
Here is dump from upa version 1.3 – for 24c128
If the eeprom dump works well at the first time, but after UPA USB V126.96.36.199 disconnects and reconnects again, it shows usb device does not recognize again. You should try one of these two solutions:
1). You should fill eeprom with FF. After connecting it, it will ask you to update eeprom. You should update and it will work well.
2). You need to change this N15. N15 is fuse, value about 0R.
