- именно _такои_ же девайс но

Цитата:
Был у меня подобный девайс в ремонте, только на чипе от Cypress CY7C68300

- именно _такои_ же девайс но вместо НЕк стоял Кипарис?

На НЕК датшита я тоже не нашел, а если судитъ по аналогии с Кипарисом то и ты и павел абсолютно правы, поетому сдампитъ потроха еепромины будет наилучший варинат, жалъ токо я никак не найду свои читателъ...

Цитата:
The contents of the 256-byte (2048-bit) two-wire serial EEPROM are arranged as follows. The column labeled “Required
Contents” contains the values that must be used for proper operation of the EZ-USB AT2.

Цитата:
During the power-up sequence, internal logic checks the I2C-compatible port for an EEPROM whose first two bytes are both
0x4D. If a valid signature is found, the EZ-USB AT2 uses the values stored in the EEPROM to configure the USB descriptors for
normal operation. If an invalid EEPROM signature is read, or if no EEPROM is detected, the EZ-USB AT2 defaults into Board
Manufacturing Test Mode.

Цитата:
In Board Manufacturing Test Mode, the chip behaves as a USB 2.0 device but the ATA/ATAPI interface is not active. The EZ-USB
AT2 allows for reading and writing an EEPROM and for board level testing through vendor specific ATAPI commands utilizing the
CBW Command Block as described in the USB Mass Storage Class Bulk-Only Transport Specification
