| - EE Electronics ESLA201A |
| - Robomotic MiniLogic |
| - Robomotic BugLogic 3 |

| - USBee SX |
| - All Cypress FX2 eval boards with stock Cypress VID/PID, including: |
| - Lcsoft Mini Board |

| and support for analog signal acquisition (on devices which have these |
| capabilities) will be added later. |
| * ASIX SIGMA driver: |
| - Add support for the ASIX SIGMA2. This requires the latest version of |
| the SIGMA/SIGMA2 firmware files. |

| accidentally deleted upon 'make distclean'. |
| * ChronoVu LA8 input file format: Improve autodetection of the file format. |

| exactly this amount of bytes). |
| |
