<p class=MsoNormal>Asi mate pravdu, s linuxem kamos nejsem, takze o FTDI
chipech a linuxu <br>
nic nevim. Ale kdyz se divam na stranky driveru pro FTDI chipy, tak tam <br>
maji u driveru pro linux vypsany snad vsechny chipy:<br>

Zrovna dneska jsem si trochu pohral s prevodnikem FT232R ve WinXP. <br>
Pouzivame jej jako prevodnik na RS-485 a IrDA - virtualni COM port a <br>
funguje to dobre.<br>
FT232R ma v sobe eeprom a v ni seriove cislo chipu, takze i kdyz jej pak <br>
prehazuju do jinych USB portu, vzdy jej pozna a priradi mu stejny <br>
virtualni COM. U FT232BM bez EEPROMky vytvoril v jinem USB portu jiny COM.<br>
Zkousel jsem prepsat i EEPROM, dat si tam svuj nazev, take bez problemu. <br>
Pak jsem upravil 2 inf soubory a napsal tam zase svuj text a ve <br>
windowsech ve spravci zarizeni to bez problemu vidim jako svoje zarizeni <br>
s nazvem co jsem si vymyslel. Akorat widle hlasi pri instalaci, ze <br>
driver neni podepsan - original je.<br>
Muzu mit pripojeny treba 2 kusy, kazdej vytvori svuj virtualni COM a oba <br>
jedou najednou bez problemu. Prehazovat na USB portech lze take v <br>
pohode. Takze pod WIN se jim to povedlo.<br>
