That's what I found in another (linux related) VID + PID data base:
174c ASMedia Technology Inc.
07d1 Transcend ESD400 Portable SSD (USB 3.0)
1151 ASM1151W
1153 ASM1153 SATA 3Gb/s bridge
2074 ASM1074 High-Speed hub
3074 ASM1074 SuperSpeed hub
-> 5106 ASM1051 SATA 3Gb/s bridge
5136 ASM1053 SATA 3Gb/s bridge
51d6 ASM1051W SATA 3Gb/s bridge
-> 55aa ASM1051E SATA 6Gb/s bridge, ASM1053E SATA 6Gb/s bridge, ASM1153 SATA 3Gb/s bridge, ASM1153E SATA 6Gb/s bridge
The read out PID via flash tool seems to be wrong (55AA indicates ASM1051E) but in reality it is a ASM1051 without E.
Does it matter if 55AA or 5106 is used? Should I correct it (5106 resp. ASM1051)?
I would suggest that you identify the serial EEPROM/flash and short the DI or DO pins while powering up the enclosure.
This will invalidate the external memory and cause the bridge to operate as a generic device until the next power cycle.
If the result is what you want, then you could permanently disable the chip.
It's a serial EEPROM 25LC512:

Can shorting SI or SO to GND kill the IC?
