## 3.2 A little more detail on the flash files
The flash files that are included with TinI/O don't have a Linux-compatible editor and therefore can't be tweaked to fit one's needs ideally. However, this can be done in a Windows environment using a dedicated program from Cypress. With it you can modify the chip's configuration without being limited to the premade flash files. However, some USB-related settings are and **have to be** the same regardless of the use case to ensure compatibility with TinI/O program.
Use case independent properties:
| Max. Current drawn from USB | 350mA |
And they provide the following configurations:
| _parameter_ | _value in `5-5_decoded.cyusbd`_ | _value in `3-3cs_decoded.cyusbd`_ |
|-------------|---------------------------------|-----------------------------------|
| Max. current drawn from USB | 350 mA | 350 mA |
| USB device class | PHDC | PHDC |
| I/O logic level | LVTTL | LVTTL |
| USB Vendor ID | 0x04b4 (Cypress) | 0x04b4 (Cypress) |
| USB Product ID | 0x0002 | 0x0002 |
| Manufacturer string | TinI/O | TinI/O |
| Product string | 5/5 | 3/3CS |
| UART Tx pin | 5 | 5 |
