I'm writing about PS/2 mice, not USB. And the info is there, have a look here: http://www.dqcs.com/logitech/PS2ppSpec.htm and I have no problem retrieving it, for example using this simple patch over mouse.c: @@ -1416,6 +1416,9 @@ dw = (pBuf[2] & 0x08) ? (pBuf[2] & 0x0f) - 16 : (pBuf[2] & 0x0f); break; + case 5: /* wireless status type packet */ + xf86Msg(X_INFO, "%s: battery level: %d, RF channel: %d\n", pInfo->name, + pBuf[2] & 0x07, (pBuf[2] >> 3) & 0x07); case 0: /* device type packet - shouldn't happen */ default: buttons |= (pMse->lastButtons & ~0x07); (I have Logitech Cordless MouseMan Optical). What the problem is is getting the info from the driver to a client (once it has been read from the mouse). I hope that clears it out. -- Divide by Zero (is not really dividing by zero) _______________________________________________ Devel mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/devel
