Hi,
Yesterday I've purchased Tyros-1 and wanted to upgarde firmware. Installing USB-MIDI drivers is fine, as I think, as Reaper (DAW software) properly reads USB/MIDI ports and I can record and replay sounds.

Yamaha’s Premier Music Workstation – Unsurpassed Quality, Features and Performance Tyros4 - Downloads - Arranger Workstations - Keyboard Instruments - Musical Instruments - Products - Yamaha. USB-MIDI Driver V3.1.1 for Win 7/Vista/XP (64bit) (Previous version). Download anime sekirei s2 anime batch 2017. Sure to use the latest versions of the software available on this Yamaha Pro Audio site.

Installer says 'Can't open YAMAHA USB MIDI driver'. Tyros is connected via USB cable, and as I wrote, is usable under Reaper. During installation it (Reaper) is turned off, of course. Driver no matter it is upgraded (previously I've had few other Yamahas with USBtoHost ports, so different versions of MIDI-USB drivers has been installed completely fine), or installed from the scratch. I've got Logitech webcam connected (installer says to disconnect all USB devices except mouse and keybaord, but is this really THAT ?). Have you had, guys, similar issue ?
Thanks for any clues
(can't check unplugging USB camera now, because Tyros is being refurbished at this moment, but I can't wait as well and I'd like to know what was your experience with this matter, if any).

UPDATE:
It's not webcam matter, I think it's a 64-bit drivers issue which didn't allow me to use MIDI ports the way Yamaha intended to. They say, for example, to configure MIDI ports as '0-1' whether my USB drivers allow use '1-2' or '1' config only (and '1' is blinking all the time, like constant error) - I've tried with 64-bit Windows 7 and 64-bit Vista.
I have no 32-bit OS at home :/ so I've tried (lol, really stupid idea, but I've tried this) using VirtualBox and 32-bit XP which I've got somehow. It gave me well-known message 'can't open Yamaha USB MIDI driver' and windows with MIDI config appeared, so I've set up MIDI 1-1 (in-out) and launcher started.. Tyros went to upgrade mode with gray screen, I've clicked OK, and then.. installer hung up lol.. with Tyros gray screen saying 'do not turn off keybaord, otherwise it becomes unusable'. I've kicked somethiong in my room 'happy' like hell, but had no other option, like turn it off. Once turned on again it seemed to work, anyway - apparently installer sent init message only with no other data before it prematurely terminated, so looks like I've had very lucky day yesterday
I know I could buy 14 floppies (unrealistic), or swap floppy to floppy-USB emulator and format one stick with first 14 floppies and give a try (untested). but I'd prefer to force this direct USB method. All I need to know what is causing issues. My current 1.2 Firmware - for example - does not store OTS settings for left hand (?). and left hlod option.
RESOLUTION (update):
Yamaha support confirmed that floppy drive is the only way to upgrade firmware in Tyros-1. So I've put USB-floppy emulator there and gave a try. It worked finally, but there were few heart attacks in the meanwhile
First time - Tyros didn't recognize inserted media (floppy #1 as I remember), switching disk numbers didn't help. But removing & inserting whole USB pendrive helped, lol. In any other cases - switching disk numbers was fine.
. and with disks number 10 and up - Tyros didn't recognize the filenames. It turned out my linux software that I use for preparing pendrive for 16 smaller virtual drives used obsolete filesystem and I had to ammend script manually (msdos to vfat).
Maybe someone finds this helpful.
