title: Plugin: Parade USB Hub
---
Parade USB hubs such as PS5512 have a built-in SPI-Master engine for programming external SPI ROM flash. The USB2.0 hub device can do control transfers to control an internal mailbox.
The daemon will decompress the cabinet archive and extract a firmware blob in a packed binary file format.
This plugin supports the following protocol ID:
com.paradetech.usbhub
These devices use the standard USB DeviceInstanceId values, e.g.
USB\VID_273F&PID_1001
- Load 384KB SPI ROM data buffer
- Specify target SPI ROM bank, ex: HUB_FW#1 or HUB_FW#2
- Set UFP Disconnect Flag register to notify firmware that we are doing firmware update
- Acquire SPI Master
- Unprotect SPI ROM bank
- Erase SPI ROM bank
- Update SPI ROM bank
- Protect SPI ROM bank
- Verify checksum for the just updated SPI ROM bank
It takes around 90 seconds to update the FW#1 64KB firmware. FW#2 is the factory default with a known good firmware. Please do a full power cycle to make new firmware take effect.
The vendor ID is set from the USB vendor, in this instance set to USB:0x273F
This plugin uses the following plugin-specific quirks:
Set the chip used, e.g. ps188
or ps5512
, defaulting to the latter.
