Tip connection using a usb hub

Hi,
I am trying to set up a tip connection using a usb hub.
I have the following in my /etc/remote file:
hardwire:\
:dv=/dev/term/0:br#9600:el=^C^S^Q^U^D:ie=%$:oe=^D:
I am getting the message "link down" when I issue the tip command.
any help would be appreciated.

Hmm, "tip" works with serial lines, and an "usb hub" is a device on an usb bus. There's a device missing
in your setup, an "usb serial port" device.
Another question: Where is the usb hub and usb serial port device connected? To an USB port on a PC?
Or an USB port on the Sun?

  • I can't print wirelessly using Airport Express.  I have my HP printer connected to a USB hub, and the hub to the Airport Express, but when I select the HP from the printer list, my MacBook says the printer is "off-line" - even when it is not.

  • Can I use a USB hub to connect to multiple USB ports from one GPIB-USB-HS?

    I have one instrument which has a GPIB-USB-HS connected and the USB cable is connected to a USB hub. Can I have multiple PCs to connect using USB hub at their respective USB ports? If so, how many PCs can I connect using the USB cable?
    I have downloaded the latest NI-VISA from the website.
    Solved!
    Go to Solution.

    You would first need a hub that allows you to switch between multiple pc's and then only one pc at a time would be connected and in control.
    When you buy this special type of hub, one of the specs is how many pc connections it has.

    That's not possible, it was designed to handle one device at a time.

  • Can I connect both a printer and a hard drive to time capsule using a usb hub?

    since there is only one usb port on a time capsule, can i connect a printer and a hard drive using a usb hub?

    You can use a USB hub if you need one to connect an external drive and a printer. See > http://support.apple.com/kb/HT2421?viewlocale=en_US&locale=en_US

  • Possible/Safe to use a usb hub on Airport Express?

    I'm about to purchase my second external hard drive for backups and I was wondering if it is safe/plausable/possible to plug a usb hub into the USB port of the Airport Express to connect my two hard drives (and maybe a printer) to connect all three of these devices to my local network? Has anyone tried this? I'd to know before I get the usb hub

    Unfortunately, the AirPort Express will not support a hard drive connected to its USB port. Only compatible printers are supported.
    So, while you could connect a powered USB hub to the AirPort Express, it would only function correctly with multiple printers.
    To support a hard drive, you would need an AirPort Extreme.

  • HT4101 When I connect using the USB version I get a message on the ipad saying "the attached accessory uses too much power. What can I do?

    When I connect using the USB option I get a screen on the ipad which says "Accessory Unavailable. The attached accessory uses too much power"
    What should I do please?

    I believe your camera uses a micro SD card. The CCK accepts the full size SD card. Do you have a SD card adapter to plug the micro into?

  • Could I use a USB hub to connection both a printer and an external hard drive to the time capsule?

    I am planning on purchasing a new router.  The Time Capsule looks amazing.  However, I have Macs and PC's in my how.  So, I need to know if I can connect a printer (for all computers) and external hard drive (for the PC's) by way of a USB hub on the Time Capsule.  I've read that you can do this with the Air-Extreme.

    Couple of comments:
    You will need to use a powered USB hub to connect multiple devices to the USB port on the Time Capsule
    The hard drive for use with the PCs will not be compatible for use with the Time Capsule if it is currently formatted for Windows NTFS, which it likely may be if you have been using with the PCs.
    Same info applies to the AirPort Extreme.
    The following hard drive formats would be supported:
    Mac OS Extended (Journaled)
    MS DOS FAT32

  • Connecting iPhone through USB hub

    I have a weird problem. When I connect the iPhone through a USB hub, nothing happens. It doesn't synchronize, it doesn't charge. When I connect the iPhone directly to the computer, with the same cable, it works as supposed.
    The weird thing is, I have been connecting the iPhone successfully through this (powered) hub for half a year. But suddenly it doesn't work. Everything else connected through the hub works fine.

    You're going to want a USB hub that comes with an AC adapter: the iPhone will draw as much power from the port as it reasonably can, and prefers up to 1 A (USB spec is 500 mA) at 12 V to charge as quick as possible. This tends to lead to undervolt situations on the bus when other devices suddenly draw more (a mouse wakes up, a HD spins up, et cetera).
    I use my iPhone 3G with a dock on a USB hub that's powered, and have had minimal issues. This isn't an endorsement, just FYI.

  • Is it possible to use a USB hub on a new MacBook Pro with Maverickss?

    I have used a powered Q-Store USB2 hub on first my old trust MacBook with the 13 inch screen running System X.6.8 for years; then I switched it over to my new 13 In. MacBook Pro (non retina) with Mavericks X.9.2 and it still works great. It is powered and seems to run a full load including USB hard drives, camera when wanted, cooling pad with fan, printer/scanner/copier combo, charging a MP3 player or Galaxy S4, apple mouse and keyboard, all with no trouble and no drop outs. I let an old Firewire 400 or 800 hard disk stay with my old Macintosh for now as it mirrors it, but sometimes hook it up with no problem except it gets hot.
    I have a new USB3  WD Passport 3 hard drive and a 32 gb USB 3 memory stick. I wanted to put these on a USB3 hub and use one of the ports for the faster items. I can run either my WD My Passport 3 Gb drive that I use to mirror my internal drive as long as it is alone. I can also plug a 32 gb A Data memory stick in fine alone except things get a bit snug, and there's no more room on the USB 2 hub for the memory stick. If I do not use a hub for the one port I have to either use the Hard Drive or the memory stick, not both. I was using the memory stick to port files back and forth between my old and new computers at least for a while. The USB 3 peripherals work reliably when plugged in alone, but the moment a hub gets in the picture even if only one item is plugged into it, things drop in and out. It does not matter if it is the powered USB 3 hub or the non-powered Anker USB 3 4 port hub. The USB 2 items simply work but the USB 3 ones only work alone. I have looked at the power specifications. It seems like one hard drive uses all of the power the hub can put out.
    It looks like the USB 3 is rather limited on Macintosh computers is all I can conclude. There may be extra speed, but what good is it if you can only run one peripheral at a time? It seems like even a hub stresses it unless it is a hub and a memory stick or two. I even changed to system settings to keep my hard drives from going to sleep, but still it drops out randomly if hooked to a hub and runs perfectly when plugged in directly. I had hoped to use it for an emergency start up disk if needed, though I must say the rather incredible StoreEdge Micro SDX card works great for that purpose and seems to belong.
    That old USB 2 hub, even with a smaller one plugged in with 2 portable hard drives still works flawlessly on the other port and never drops out.
    I have not tested the Firewire 800 port long enough to decide, except it gets hot if it reads very long.. The old Firewire 800 / USB 2 hard disk has more than one port on it unlike so many today. I had to use a Firewire 800 to 400 cable for my old computer. Anyway it works in either computer and stays mounted even when asleep.
    Is it possible to use a USB 3 hub with more than one peripheral on a 2012-2013 13 inch MacBook Pro computer with Mavericks? If so which one works? It cannot be good for hard disks to randomly disconnect and reconnect without being dragged to the trash.

    no you can't - you have to upgrade it to 16GB yourself.
    you can get your RAM from newegg.com, macsales.com.
    the RAM you need is 16GB (8GBX2) DDR3 1600MHz DDR3.
    upgrading the RAM yourself will not void your warranty.
    you need a #00 Phillips Screwdriver - 10 screws at the bottom - 7 long ones and 3 short ones - just remember where they go when you put the screws back in.

  • IPod tells me I can get faster connection if I use different USB hub

    I have 6 USB ports on my computer. All are 2.0. The iPod is plugged into one of the 6. Is iPod asking for a 3.0 USB port? In which case I can ignore the request, right?

    Thanks phira360, for the input. I understand and appreciate your advice. The ports act correctly, yet I continue to get this message regarding connect to a faster port.
    I wish I understood how Windows, iTunes and my iPod talk with each other.
    My 4 gen Nano manual says to connect it to a 2.0 USB. My Win 7 computer says it will be faster if I connect the iPod to one of the high speed connections on my computer. It then provides a list of high speed ports that are available. The iPod is connected to one of the available high speed ports.
    So, is iTunes asking for more speed? Has my iPod decided that it wants a 3.0 USB connection? Or, is Windows just being Windows and trying to confuse me?

  • Can I use Airport Express to connect to a printer, Time Machine Back up drive, second b/u drive, and scanner through a USB hub? if so, how?

    I have an Airport Express that connects to my printer. I'd like to add a scanner, and two back up drives (one for use with Time Capsule, another specifically for photographs backed up from Adobe Lightroom.
    The printer connects to the Airport Express through a USB hub and is recognized.  I cannot get the scanner nor either of the back up drives to be recognized.  Is there a way to do it or will I need to rely on a USB hub wired to the USB port of the MacBookPro?  If it is possible, can you walk me through the set up for each? 
    Thanks,
    Doug Earle

    I'd like to add a scanner, and two back up drives (one for use with Time Capsule, another specifically for photographs backed up from Adobe Lightroom.
    Unfortunately, the USB port on the AirPort Express will only work with a compatible printer.
    It will not work with a scanner, copier, or hard drive.
    It should be possible to do what you want by connecting a powered USB hub to your Mac and then connecting the devices to the powered hub.
    The setup for the scanner and hard drive would be covered by the manfacturers documentation, so providing specific advice for those types of products would be outside the realm of this support area.
    But, if you can provide model numbers, it is always possible that another user who is using those products might see this post.

  • Access to external drives connected to Airport Extreme via USB Hub

    I have 2 computers connected wirelessly to an Airport Extreme 802.11n base station. I have a Belkin powered USB hub connected to the USB port on the Extreme. There is a Lacie hard drive, a USB printer and a Kingston flash drive connected to the USB hub.
    The printer was connected using Bonjour and is working fine. The other devices connected to the USB hub aren't getting picked up. They did work at one point, but are no longer viewable from the computers (MAC Book and Windows XP). How can I re-configure the Extreme or my computers so that they'll work again?

    DLNA = Digital Living Network Alliance. DLNA works in a Server-Client fashion with the Server providing the means to stream audio/video files to the client. DLNA servers are also called media servers. The AirPort Extreme Base Station (AEBS), with an attached USB HDD at best, can perform as a media storage device ... not as a server. You would still need a media server (either hardware or software) to perform this role.
    For example, I use a software DLNA-compliant media server, called TwonkyServer. I run this server on one of my Mac minis. It gets its media files that are stored on a USB HDD attached to my 802.11n AirPort Extreme Base Station (AEBSn). TwonkyServer then streams these video files to my Xbox 360 which performs as a media client/player.

  • Using with a USB Hub

    Hi. Right now I have an old iMac, and I use a USB hub (I have way too many USB devices that I like to have connected at once). If I were to switch to a Macbook along with one of the new 24" LED displays, would I still be able to connect the USB hub to the back of the display, or should I not do this since the display technically functions as a USB hub itself?

    USB hubs can be used with other USB hubs as long as the hub they plug into has power, such as the display hubs.

  • Using the integrated USB hub on my Thunderbolt Display causes troubles

    I just purchased a MacBook Air and a Thunderbolt Display. Unfortunately, when I connect USB plugs to the Displays buildin USB hub, I'm getting severed connections all the time (USB-Connection lost, Firewire-Connection lost, Ethernet-Connection lost...).
    I really loved the idea of not having to use external USB-hubs as this only clutters my desk - but the Displays internal hub cannot be used savely (I have a couple of hard drives connected via FW and USB to the Display - this has already resulted in data loss (fortunately I had a backup).
    As soon as I'm NOT using the Display's USB ports everything is fine (the Display's FireWire and Ethernet ports do not seem to cause any trouble).
    Anyone else seeing this?

    Plugging an additional USB hub into the integrated USB hub extends the problematic behavior even further.
    If I eject a thumb drive from a USB hub that's attached to the Thunderbolt display hub (for example), it will never recognize that thumb drive again, on any of the USB ports on the display or any additional hub connected to the display, until I reboot with no added USB hub, and then reconnect an empty hub, and then add devices one at a time.
    I've also noticed that while some devices drop off, some continue to show up in the system report, even when they have been properly ejected or disconnected. Refreshing the system report doesn't update with what's really going on...
    Weird... So since mountain lion, I don't disconnect any USB devices from the Thunderbolt display, unless I really, truly must.
