+Buna Ziua tuturor,
+
+Am o placa de baza, cu mare probabilitate J-542B, Chipset Ali M1542/M1543,
+Aladdin-V chipset.
+Vreau sa ma conectez la ZAPP, din Linux, pe portul USB
+Un lucru este absolut cert: portul exista si este functional intrucit ma pot
+conecta din XP.
+In Control Panel-ul din XP la "Sectiunea USB" scrie:
+ALI PCI to USB Open Host Controller
+USB Root Hub # Iar sistemul il asigneaza pe COM 4 !!??!!
+L-am lasat in pace ca de mers merge........
+
+Ies din Windows. Pe alta partitie este RH-8.0
+Ma duc in LINUX, RH-8.0, kernel-ul distributiei, nemodificat.
+Inserez modulele:
+1) modprobe usbcore # totul e OK
+2) modprobe usb-ohci # Sistemul imi spune:
+" usb.c: USB device 2 (vend/prod 0X678/0/2303) is not claimed by
+any actine driver.
+#si cele doua module sunt inserate.
+3) Instalez scriptul celor de la ZAPP ( install_hy.sh, e functional, la
+slujba lucreaza excelent)
+4) Incerc conectarea si dau comanda "zapp"
+Modific (de nervi) in /etc/ppp/peers/hyundai-zappmobile de la /dev/ttyUSB0
+pina la /dev/tty/USB4
+si nimic bun, in tail -f /var/log/messages imi zice:
+"Failed to open /dev/ttyUSB0 (#sau cit o fi): No such device.
+Am incercat si pe /dev/ttyS0.......3 si zice:
+Can't get terminal parameters: Input output error
+
+Va rog indrumati-ma si spuneti-mi ce sa fac ca sa lucreze ZAPP-ul  (si) in
+linux, (ca in windows e clar ca e OK ) ??
+
+Va multumesc

+In sfarsit am rezolvat crapu, cu ajutorul lui James McQuillan (taticul
+LTSP). E foarte simplu si foarte nedocumentat, 16 mega NU sunt
+suficienti pentru o statie desi peste tot se zice ca si 8 sunt ok, motiv
+pentru care e imperativ necesar sa se foloseasca swap-over-NFS care
+merge super bine (stiu ca majoritatea au o reticenta in a folosi
+swap/nfs, don't be shy, it rocks). Am mai adaugat 64 de ram pe NFS si
+acum rupe tovarashu' terminal, am load 2 la server si totul merge f
+bine.  
+Un 32 de MB sunt minim, 8/16 cat are sistemul + 32 e safe. 
+Sper ca observatia asta sa apara in viitoarea versiune a documentatiei
+ce vine cu LTSP, cel putin asa mi s-a promis.
+
+You've got yourself a happy smilin' motherfucker.
+
+Good fight, good night.
