Usb cihazlarına veri yazma ve usb cihazlarını listeleme

Mesaj gönderen seci20 »

Ustalarım kolay gelsin. Sony cihazlar için bir program yazıyorum ama usb dosya yazdırma kısmında malasef takıldım. Normal internette olan mah.usb, usb detector,nrlibcomm gibi eklentileri kullandım ama yazmayı bir türlü başaramadım. İnternetteki listeleme yöntemleriyle sadece usb diskleri listelemeyi başardım malasef baya uzun süredir araştırdım ama malasef listeleme işlemini başaramadım. Bu konuda yardımcı olabilirmisiniz.

Kullandığım unitler.

Selamlar,
WinUSB diye bir şey görmüştüm SourceForge'da var. Hem detect ediyor hemde Read/write package sent edebiliyor diye biliyorum.

Onunla denediniz mi?

Selamlar,
Önerebileceğim şey,
Programı Debug edin, hata verilen satır ve verilen hatayı kopyalayıp internette bir aratın bakalım. Benzer konularda sıkıntı yaşayanlar vardır mutlaka.
Stackoverflow'da benzer konular görmüştüm.
Bu şekilde bir deneyin bakalım.
